Dear Dr. Lapid, Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process. Please submit your revised manuscript by Sep 05 2024 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org . When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.
If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter. If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols . Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols . We look forward to receiving your revised manuscript. Kind regards, Abdolvahed Narmashiri Academic Editor PLOS ONE Journal Requirements: 1. When submitting your revision, we need you to address these additional requirements. Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. 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 2. We noticed you have some minor occurrence of overlapping text with the following previous publication(s), which needs to be addressed: https://www.ajgponline.org/article/S1064-7481(24)00192-1/abstract In your revision ensure you cite all your sources (including your own works), and quote or rephrase any duplicated text outside the methods section. Further consideration is dependent on these concerns being addressed. 3. We note that the grant information you provided in the ‘Funding Information’ and ‘Financial Disclosure’ sections do not match. When you resubmit, please ensure that you provide the correct grant numbers for the awards you received for your study in the ‘Funding Information’ section. 4. When completing the data availability statement of the submission form, you indicated that you will make your data available on acceptance. We strongly recommend all authors decide on a data sharing plan before acceptance, as the process can be lengthy and hold up publication timelines. Please note that, though access restrictions are acceptable now, your entire data will need to be made freely accessible if your manuscript is accepted for publication. This policy applies to all data except where public deposition would breach compliance with the protocol approved by your research ethics board. If you are unable to adhere to our open data policy, please kindly revise your statement to explain your reasoning and we will seek the editor's input on an exemption. Please be assured that, once you have provided your new statement, the assessment of your exemption will not hold up the peer review process. 5. 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. Additional Editor Comments: This protocol study provides evidence for the use of tDCS as an adjunct to standard care in the treatment of TRD in hospitalized patients. However, I have significant concerns regarding the methodological and scientific standards of this paper. A complete rewrite and reorganization are necessary to align it with accepted scientific standards. 1. Introduction: Remove the section titles and rewrite the introduction to present a coherent narrative. 2. Results: Add a dedicated results section to report pre- and post-tDCS outcomes, including measures of depression and cognition. 3. Methods: Rewrite the methods section to adhere to scientific standards. 4. Results Reporting: Ensure your results include: o Depression measures (Montgomery-Asberg Depression Rating Scale (MADRS)) o Cognitive measures (Stroop Test, Revised Hopkins Verbal Learning Test (HVLT-R), Digital Symbol Coding Test (DSCT)) o EEG changes in peak alpha frequency (PAF) o Cerebral hemodynamic changes (functional near-infrared spectroscopy (fNIRS)) o Attention to statistical analysis and accurate reporting in the results section. 5. Discussion: Remove the section titles and discuss the results in the context of the study protocol. [Note: HTML markup is below.

You may also include additional comments for the author, including concerns about research or publication ethics. You may also provide optional suggestions and comments to authors that they might find helpful in planning their study. Reviewer #1: 1. This paper outlines a protocol to investigate the feasibility of implementing a 5-day tDCS treatment in hospitalized patients with TRD. The research also aims to explore the potential positive effects on depression and cognition and the neurophysiological mechanisms underlying tDCS. The authors did not indicate the specific descriptive statistics that will be used to summarize the data for continuous and categorical variables. They only mentioned descriptive statistics, which are too broad. 2. Since you are measuring the outcome measures before and after treatment for the same patients, the paired t-test or the non-parametric alternative will be more appropriate due to the correlation in the outcome measures. 3. Kindly state the statistical software that will be used for the analysis and at what level of significance the null hypothesis of no treatment effect will be rejected. 4. There was no justification for selecting 10 patients. There was no power analysis or sample size estimation to justify the choice of 10 and no reference to previous studies or expert documentation to justify the selection of 10 patients for the study. 5. Authors must provide references for the definition of feasibility outcomes. Some were set at >70% and others >80%. There must be references or justification to support the cut-off points or the 70% and 80% thresholds. Why not 90%, 50%, etc.? Kindly provide detailed justification or references to support the cut-off points. 6. Again, the authors indicated that treatment response will be defined as 50% or more improvement in MADRS score post-treatment from pre-treatment, but no justification was provided as to why they are setting the cut-off at 50% and not any other threshold. My concern is that setting the threshold at different cutoffs can generate entirely different results and conclusions, and that is more reason why justification must be provided 7. The authors anticipate the possibility of missing data but did not indicate which statistical technique will be used to handle missing values if it does occur. This is important as only 10 patients will be studied. 8. Complete case analysis, as suggested by the authors, in the presence of missing data reduces the sample size and the power of the study. This is particularly important when the authors have decided to study only 10 patients without details on how they arrived at the number 10 and the implications for missing observations. 9. Authors may re-consider running logistic regression on just 10 observations, with the possibility of a reduced sample size to an even smaller figure below 10. Reviewer #2: Title: - Please do not use acronyms in the title. Keywords: - Please do not use the same words/expressions used in the title as keywords. Ethics Statement: - Please add information about the registration of the randomized clinical trial that will be carried out from the study protocol. Add the name and registration number to the Abstract session as well. Introduction - Line 76: What does “FDA” mean? Please write it in full before using the acronym. - In general, I found the writing of the introduction to be exaggeratedly long. Information about TMS and fNIRS is not necessary here. I suggest placing more emphasis on the main focus of the study (effects of tDCS in TRD populations). Methods - Please add information about the sample calculation. - Please add information about study blinding and randomization between active and sham. - Please indicate when the participant recruitment period will begin and the expected date for the completion of interventions/evaluations. - Explain the reason for applying tDCS twice a day. - Please include references that support your interpretations for the “feasibility”, “acceptability” and “tolerability” measures. - Please provide more details on the equipment used to measure cortical activity (EEG and fNIRS). - Do you not intend to evaluate changes in deoxyhemoglobin? Please contextualize Discussion - This section needs to be better written, it is necessary to present information about protocols of other similar studies. Furthermore, I recommend making the innovative aspect of the study more evident. ********** what does this mean? ). If published, this will include your full peer review and any attached files.
