Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: No Reviewer #2: Yes ********** Reviewer #1: The manuscript "Global, regional, and national burden of cardiomyopathy (including alcoholic cardiomyopathy and others) from 1990 to 2021: an analysis of data from the global burden of disease study 2021 and forecast to 2040" presents a comprehensive epidemiological assessment of cardiomyopathy using the GBD 2021 dataset. Overall, the topic is timely and relevant, and the manuscript provides useful insights into long-term trends. From a methodological perspective, the study is well designed. The use of age-standardized rates (ASR), estimated annual percentage change (EAPC), and the Bayesian age–period–cohort (BAPC) model is appropriate for this type of analysis, and the underlying dataset is robust. The conclusions are broadly consistent with the results, although they remain somewhat general. A clearer discussion of the implications for clinical practice or public health policy would enhance the manuscript's impact. The statistical methods are rigorous, but several descriptions, particularly those involving formulas and confidence intervals, are not fully clear, which may reduce reproducibility. It would also be helpful to elaborate on the rationale for selecting the BAPC model over other forecasting approaches. The manuscript is written in standard English and is generally easy to follow; however, the text is quite dense, and the amount of numerical detail reduces readability. The Results section, in particular, contains too many values. Or, the Abstract includes a single sentence with more than fifteen numerical values ('...4752361.3 (95% UI: 3937775.4–5566947.2), including AC: 528429 (95% UI: 439582.3–639167.4) and OC: 4223932.2 (95% UI: 3417357.4–5034257.6)...'). A language revision to simplify phrasing and reduce redundancies would be recommended. Reviewer #2: This manuscript is clearly written and presents descriptive analyses based on publicly available data from the Global Burden of Disease (GBD) 2021 study. The authors have evidently invested considerable effort in compiling and presenting long-term trends and projections. However, despite these strengths, the study suffers from several fundamental conceptual and methodological limitations that substantially limit its scientific contribution and interpretability. These concerns go beyond issues of presentation and cannot be adequately addressed through minor or moderate revision. First, there is a fundamental mismatch between the stated research objectives and the study design. Although the manuscript is presented as original research, the analyses rely entirely on pre-modelled secondary data obtained from the GBD 2021 database. The study does not introduce new data, novel analytical frameworks, or independent validation. As a result, the work remains largely descriptive and does not adequately support the broader inferential claims made in the manuscript. This represents a conceptual limitation rather than a reporting issue. Second, the study population is insufficiently defined from an epidemiological perspective. Case identification is based on ICD-9 and ICD-10 codes within the GBD framework; however, the manuscript does not sufficiently address diagnostic heterogeneity, underreporting, or regional variation in disease ascertainment. Without a clearer description of how these issues may affect the estimates, the generalizability and interpretability of the findings are limited. Third, the analytical contribution of the study is limited. The manuscript largely reproduces standard GBD outputs, including age-standardized rates, estimated annual percentage change, and Bayesian age–period–cohort modelling using existing software packages. The rationale for applying these methods specifically to cardiomyopathy is not clearly justified, and no sensitivity analyses or alternative modelling approaches are presented. Consequently, the robustness of the reported trends and future projections cannot be adequately assessed. Fourth, the conclusions appear to overinterpret descriptive and model-based results. Several statements imply implications for disease control or policy, despite the absence of causal or risk factor–based analyses. Given the observational and model-dependent nature of the data, such interpretations are not sufficiently supported. Finally, key methodological details related to model assumptions, uncertainty handling, and reproducibility are insufficiently described. This limits the ability of independent researchers to replicate or critically evaluate the analyses, which is an important consideration for publication in PLOS ONE. While the manuscript is clearly written and based on a reputable global dataset, the conceptual and methodological limitations outlined above are substantial and, in my view, cannot be resolved through revision alone. I therefore do not recommend the manuscript for publication in its current form. ********** what does this mean? ). If published, this will include your full peer review and any attached files.

Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: Yes Reviewer #2: Yes ********** Reviewer #1: The authors have adequately addressed all the points raised in the previous review round. The revision improves the clarity and coherence of the manuscript, and the responses provided are appropriate and satisfactory. I also appreciate the authors' effort in incorporating the requested changes and strengthening the overall quality of the work. Reviewer #2: I would like to thank the authors for their thorough and thoughtful revision of the manuscript and for the detailed, point-by-point responses to the reviewers’ comments. The revised version demonstrates a clear effort to improve conceptual clarity, methodological transparency, and interpretative balance. In particular, the revised Introduction more clearly positions the study as a descriptive global assessment based on GBD 2021 estimates, which improves alignment between the research objectives and the analytical approach. The expanded discussion of limitations related to diagnostic heterogeneity, underreporting, and regional variability is appropriate and strengthens the interpretability of the findings. The analytical methods employed are consistent with established approaches used in global burden of disease research, and the inclusion of an additional sensitivity analysis provides reassurance regarding the stability of the observed temporal trends. While further methodological extensions could be explored in future work, the current analyses are suitable for the aims as stated. I also appreciate the authors’ efforts to moderate the language in the Discussion and Conclusions. The implications are now framed more cautiously and appropriately reflect the descriptive and model-based nature of the data, avoiding overstatement of causal or policy conclusions. Overall, I believe that the revised manuscript provides a clear, well-documented, and methodologically sound overview of the global burden and temporal trends of cardiomyopathy. Within the scope and publication criteria of PLOS ONE, the study represents a useful contribution to the literature. ********** what does this mean? ).
