PONE-D-23-36527A meta-analysis of the association between inflammatory cytokine polymorphism and neonatal sepsisPLOS ONE Dear Dr. Hao, 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. The manuscript evaluated the link between inflammatory cytokine polymorphisms and neonatal sepsis with a meta-analysis. The authors should revise the manuscript according to the reviewers' suggestions and should respond to the reviewers point by point. Besides the reviewers' comments, I have the following observations regarding this manuscript. 1. The introduction/ literature section should be elaborated to reflect all the variations of five included genes, including sepsis. 2. A sequential trial analysis should be performed to verify that the included studies are sufficient to rationalize the studies' outcomes. 3. Due to the studies of multiple variants in multiple models, Bonferroni correction of p-value should be performed. 4. False-positive report probability (FPRP) should be included to evaluate the credibility and reliability of observed associations or effects. 5. Authors should clarify which variant/model increases the risk of sepsis and which decreases the risk. 6. The authors should minimize the grammatical errors. Please submit your revised manuscript by Mar 20 2024 11:59PM.

Review Comments to the Author Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: The manuscript on inflammatory cytokine polymorphism and neonatal sepsis has several areas for improvement: 1. The literature collection could be more comprehensive. Currently, the literature mainly focuses on the gene polymorphisms of several inflammatory factors. Whether the search scope could be expanded to cover more inflammatory factors and other biomarkers related to neonatal sepsis. 2. The statistical methods could be described in more details, for example, the statistical reasoning of Hardy-Weinberg equilibrium test, heterogeneity test, etc. 3. The results describing the associations between various gene polymorphisms and neonatal sepsis could be more clear and concrete, so that readers do not have to search for the information. It is suggested to present the statistical testing results of associations between gene polymorphisms and disease in a table form. 4. The limitations of this study could be more comprehensively described in the discussion section. Currently, only heterogeneity and sample size are discussed. Whether there are other biases that need to be explored. 5. The conclusion is a bit absolute. It is suggested to use words like "indicate", "imply" instead of "confirm", as this study cannot completely "confirm" the associations between certain genes and disease. 6. The format of references could be unified. 7. The excessive number of pictures is very inconvenient for readers. 8. The language context in the manuscript is less coherent and the writing is more mechanical, so it is recommended to have it revised by a professional with a foundation in English as a mother tongue. Reviewer #2: Reviewer’s Comments General English grammar needs to be improved, though it is comprehensible but not upto the mark. Title. The title correctly reflects the aim and scope of the research. ABSTRACT The abstract follows a logical format, outlining the background, objectives, methods, results, and conclusions. Searching multiple databases increases the likelihood of capturing relevant literature. Appropriate statistical tests are used to assess heterogeneity and publication bias. The abstract details the significant associations identified for different cytokines and genetic models. The abstract acknowledges the limitations of small sample size in some studies. i. While the abstract states associations between specific polymorphisms and neonatal sepsis, it could benefit from mentioning the direction of the effect (e.g., increased/decreased risk). ii. Quantifying the strength of evidence using measures like P values and confidence intervals would strengthen the abstract. iii. Briefly mentioning the potential clinical significance of the findings (e.g., for diagnosis or personalized medicine) could enhance the abstract's impact. Collectively, this is a well-written abstract that effectively summarizes the main findings of the meta-analysis. 1. INTRODUCTION The introduction section of the meta-analysis clearly states the importance of neonatal sepsis and its connection to inflammation and also highlights the role of cytokines in immune response and potential connection to sepsis susceptibility. It also mentions the inconsistency of previous research on cytokine polymorphisms and neonatal sepsis and also clearly describes the aim of the current study i. Though the introduction section is good but very short and broad. It could be improved by broad-to-narrow manner, to a more specific statement about the study's hypothesis or key research question. ii. Repetition. Sentences 59-60 and 63 could be combined to avoid repetition. iii. In the reviewer opinion, the meta-analysis needs to be supported by more and recent reference (if available). References are only used once in the introduction, making it difficult to assess the strength of the claims made. Consider incorporating more specific citations and evidence to support the statements. iv. Information on the specific polymorphisms explored in the study is missing. Mentioning which cytokine genes and polymorphisms will be investigated would provide better context. v. The introduction primarily focuses on genetic susceptibility and doesn't mention other potential factors influencing the association between cytokines and neonatal sepsis (e.g., environmental factors, maternal health). Briefly acknowledging these complexities would provide a more nuanced picture of the research topic. vi. Conclude the introduction section with a clear statement of the study's objectives and its potential contribution to the field. 2. Materials and methods 2.1Document retrieval The terms provided seem good, but justification for their inclusion (e.g., pilot searches, previous reviews) would support the rationale of the search strategy. Line 72. Please rephrase the sentence to. To ensure a comprehensive search for relevant articles, we combined medically relevant keywords with broader terms. Additionally, when encountering duplicate publications, we selected the one with the most complete data for inclusion in the study. For the above statement, the reviewer would like to know “How is the "most complete data" chosen among repeated studies?”. Explain in one or two lines. 2.2Inclusion and exclusion criteria The meta-analysis carefully selected relevant studies by focusing on specific designs, prioritizing newborn populations, ensuring data quality, and excluding redundant or irrelevant research. Excellent. Limiting the study to Chinese and English might exclude valuable research conducted in other languages. Consider justifying this choice or exploring translation options. Like Figure 1, almost all other figures are not visible and readable though they seem correct. The resolution could be resolved for clarity, for all figures. 2.3Literature screening Please remove the following subtitle from the text. Figures legend should be below or above the relevant figure and could be with more detailed description so that the figure looks self-explanatory. Line 88 Fig 1. Flow Chart of IL-1 Literature Screening. Line 91 Fig 2. Flow Chart of IL-6 Literature Screening. Line 95 Fig 3. Flow Chart of IL-8 Literature Screening. Line 99 Fig 4. Flow Chart of IL-10 Literature Screening Line 103 Fig 5. Flow Chart of TNF- α Literature Screening Please follow the same instructions for other such relevant descriptions. 2.5Quality evaluation Briefly justify the choice of NOS for this specific meta-analysis context. 2.6Statistical analysis Detailed and comprehensive statistical data and points are given. Excellent In the reviewer opinion, Begg's funnel plot is undoubtedly a very useful and required tool for such analyses, but not necessarily, just a suggestion that considering additional methods like Egger's test for publication bias would provide a more comprehensive evaluation, if possible, please include it in the study, otherwise not obligatory. 3. Results Overall, the results described based on the methodology are genuine. Each section effectively presents the general characteristics of the included studies, enhancing the study's transparency and allowing readers to evaluate its representativeness. 4. Conclusion Conclusions are presented in an appropriate fashion and are supported by the data. Decision. The reviewer is quite impressed by the efforts and hard work of the authors and congratulate them for such a detailed and attractive study. The article can be accepted for publication after the authors addressing the issues raised by the reviewer. ********** 6.
