The PLOS ONE style templates can be found at https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and https://journals.plos.org/plosone/s/file?id=ba62/PLOSOne_formatting_sample_title_authors_affiliations.pdf 2. Your ethics statement should only appear in the Methods section of your manuscript. If your ethics statement is written in any section besides the Methods, please delete it from any other section. 3. One of the noted authors is a group or consortium NEDICES2-RISK Group. In addition to naming the author group, please list the individual authors and affiliations within this group in the acknowledgments section of your manuscript. Please also indicate clearly a lead author for this group along with a contact email address. 4. We note that you have indicated that there are restrictions to data sharing for this study. For studies involving human research participant data or other sensitive data, we encourage authors to share de-identified or anonymized data. However, when data cannot be publicly shared for ethical reasons, we allow authors to make their data sets available upon request. For information on unacceptable data access restrictions, please see http://journals.plos.org/plosone/s/data-availability#loc-unacceptable-data-access-restrictions. Before we proceed with your manuscript, please address the following prompts: a) If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially identifying or sensitive patient information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., a Research Ethics Committee or Institutional Review Board, etc.). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent. b) If there are no restrictions, please upload the minimal anonymized data set necessary to replicate your study findings to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. Please see http://www.bmj.com/content/340/bmj.c181.long for guidelines on how to de-identify and prepare clinical data for publication. For a list of recommended repositories, please see https://journals.plos.org/plosone/s/recommended-repositories. You also have the option of uploading the data as Supporting Information files, but we would recommend depositing data directly to a data repository if possible. Please update your Data Availability statement in the submission form accordingly. 5. In the online submission form, you indicated that regarding data exchange, the Ethics Committee for Research of the Hospital Universitario 12 de Octubre approved this research without considering the option of data sharing. The data contains sensitive clinical information about the patient, so there are ethical and legal restrictions to sharing the data set. The data are part of the NEDICES2-RISK study and can be requested by contacting the Primary Health Care Research and Innovation Foundation (FIIBAP) in the Community of Madrid at the email address fiibap@salud.madrid.org for the request of data All PLOS journals now require all data underlying the findings described in their manuscript to be freely available to other researchers, either 1. In a public repository, 2. Within the manuscript itself, or 3. Uploaded as supplementary information. This policy applies to all data except where public deposition would breach compliance with the protocol approved by your research ethics board. If your data cannot be made publicly available for ethical or legal reasons (e.g., public availability would compromise patient privacy), please explain your reasons on resubmission and your exemption request will be escalated for approval. 6. If the reviewer comments include a recommendation to cite specific previously published works, please review and evaluate these publications to determine whether they are relevant and should be cited. There is no requirement to cite these works unless the editor has indicated otherwise. 7. Please review your reference list to ensure that it is complete and correct. If you have cited papers that have been retracted, please include the rationale for doing so in the manuscript text, or remove these references and replace them with relevant current references. Any changes to the reference list should be mentioned in the rebuttal letter that accompanies your revised manuscript.

Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: Yes Reviewer #2: Yes ********** Reviewer #1: First of all I should say Authors did really valuable work on comparing CVR and cognitive performance, I just give some recommendation to improve their work: How authors follow potential confounders in their studies? How authors address recall bias of cohort study? Because Data extract from cohort study. Explain how the study size was arrived at? Explain how missing data were addressed? Indicate number of participants with missing data for each variable of interest. Reviewer #2: The introduction is comprehensive and well-referenced, giving a clear overview of the global and national context of dementia and cardiovascular disease. It correctly emphasizes the importance of modifiable risk factors and the need to study these relationships in Mediterranean populations. That said, the section could be more focused. Several paragraphs repeat well-known information on dementia trends and cardiovascular epidemiology. The rationale for using the REGICOR and FRESCO equations in relation to cognition appears late and could be highlighted earlier. The authors convincingly justify the inclusion of sex-stratified analyses, given known biological and lifestyle differences. However, the introduction would benefit from a more explicit hypothesis and a brief conceptual framework linking cardiovascular pathology (e.g., microvascular damage, inflammation) to specific cognitive domains such as memory and processing speed. Selection bias: Excluding participants with prior cardiovascular events or those taking lipid-lowering drugs (for FRESCO) may skew the sample toward healthier individuals, underestimating the true relationship between CVR and cognition. Outcome measurement: Although the neuropsychological battery is broad, the brief nature of some tests (e.g., 6-item recall, short fluency task) may reduce sensitivity to subtle cognitive differences. Statistical approach: Dichotomizing cognitive scores into quartiles (≤25th percentile vs. >25th) leads to a loss of information and power. Modeling continuous outcomes could have provided more nuanced results. Additionally, the use of multiple comparisons without correction raises the possibility of false-positive findings. Residual confounding: Important variables such as diet, alcohol intake, sleep, and socioeconomic status were not considered, though all are known to influence both cardiovascular and cognitive health. The discussion section appropriately interprets the main results within the context of existing literature. The authors correctly note that their findings align with prior studies showing that higher cardiovascular burden correlates with poorer cognitive function. They also highlight that memory and processing speed were the domains most affected—consistent with vascular contributions to cognitive decline. Nevertheless, the discussion could be more critical in tone. Several points could be strengthened: The possibility of reverse causation should be explicitly addressed. Mechanistic explanations (e.g., cerebral microvascular damage, systemic inflammation, impaired perfusion) are only briefly mentioned and could be elaborated. The observation that smokers and ex-smokers performed better in some tests is intriguing but counterintuitive; this finding deserves cautious interpretation and deeper exploration, as it may reflect cohort or survivor effects rather than a genuine protective association. The authors could also discuss the implications of their findings for preventive strategies in primary care, particularly since REGICOR and FRESCO are tools already used in clinical settings. ********** what does this mean?.

Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #3: Yes ********** Reviewer #3: The authors have provided very detailed and comprehensive responses to previous reviewer comments. The changes they made to the manuscript in response to these comments have substantially improved the quality of the work. The additional modifications of the analysis that the authors made beyond what was requested by the reviewers (highlighted with blue in the text) are well justified and indicates a critical and precise approach to their own work, which is commendable. The study overall is well justified, the analysis is done carefully, and the interpretation of the results is mostly balanced. I only have a few fairly minor comments: 1. While the authors provide a clear flow chart for how the analytical sample size was arrived at (Figure 1), they should describe this process much clearer in the text. For example, it is not clear that if the initial sample of 962 participants included only people between the ages of 55-74 years, why did they have to exclude a further 68 individuals who were 75 years or older when the REGIDOR score was analysed. In lines 138-141 on page 6, they should also mention the final sample sizes for the two scores. Particularly for the FRESCO score, a very large proportion of participants were excluded due to taking lipid lowering agents, and this needs to be explicitly presented in the text. I`m also wondering whether the differences that we see between the REGIDOR and FRESCO score results are due to these differences in the analytical sample sizes, or due to real differences in the strength of the associations regarding these two scores. 2. I would also suggest that the main findings as described in lines 425-427 (page 24) should be much more nuanced. It is true that the results indicate significant inverse associations for some of the cognitive function indicators, but there were several non-significant associations as well. Therefore, the blanket statement of both risk scores being associated with poorer cognitive performance is not correct. 3. The authors did not really respond to the comment regarding multiple testing. As previous reviewer 2 correctly mentions, when so many associations are examined simultaneously, the issue of multiple testing and possibility of false positive associations may occur. As a minimum, I suggest mentioning this in the Limitations section of the manuscript, or maybe considering the application of Bonferroni correction or similar approach. ********** what does this mean?.
