Additional Editor Comments: Dear Dr Biftu, Thank you for submitting this interesting paper, but there are many issues needs attention before publication. If you consider the Bayesian model as a novel (applied since 1976), as raised by Reviewer #2, you have to do methodological comparison with conventional models. I could see that labels for your convergence algorism assessment are missed and confusing for readers. Besides, few your plots are hard to visualize if converged or not. Please provide the details as an appendex. Additionally, it is not clear which form of Bayesian you applied in your analysis (informative, non-informative). Major concern, your discussion is too shallow and the possible explanations are not plausible. Please also include implication your study for policy or other context. Please address the comments raised by the reviewers. [Note: HTML markup is below. Please do not edit.] Reviewers' comments: Reviewer's Responses to Questions Comments to the Author 1.

Even within the abstract and introduction, there are multiple grammatical issues that make it difficult to read. Editing by a colleague or writing service with strong English skills is needed. Abstract: • It would be better if the abstract could be structured as follows: background, methods, results, and conclusion. • As a justification for the study, you stated, "Most studies conducted in Ethiopia have utilized standard models employing maximum likelihood estimation with small sample sizes." But it could be better if you describe the limitations of those standard models and the advantage of Bayesian rank likelihood-based estimation over the standard models. • The abstract should explain at least the data source, the study population, and the sample size. • The abstract should be a stand-alone document. Some of your statements in the abstract are not standalone. For example, you stated, “The prevalence of low birth weight varies across different regions of the country, highlighting the need for targeted interventions in areas with a higher prevalence." This may need further clarification where the prevalence is high. • The study revealed significant associations between birth weight and the mother's age, number of antenatal care visits, birth order, and BMI. What is new? The association between low birth weight and those factors is well known and documented by several previous studies. It is better if you magnify or focus on a new and untouched variable. • As a recommendation, you said, “It is essential to implement community-based health promotion prioritizing antenatal care follow-up and maternal nutrition.” How? Where is the evidence-based intervention (i.e., community-based health promotion intervention)? Why not facility-based? • Overall, in the abstract, I couldn’t find the answer to your study objective: to estimate parameters and provide a nationwide estimation of low birth weight and its risk factors in Ethiopia. At least you have to present the magnitude of LBW according to your estimation. Background • Please provide a comprehensive review of the epidemiology of LBW (magnitude, distribution, and determinants) in Ethiopia. • In the background, you wrote, “According to [15], in the presence of ordinal variables, a maximum likelihood-based method yields estimates with substantial bias and inaccurate coverage probabilities.” Explain why these models are biased. • In the background, a bit more detail is needed about the Bayesian rank likelihood method in the latent traits model. Methods and Materials • There are nine regions. Are you sure? Currently, there are twelve regional states and two chartered cities (Addis Ababa and Dire Dawa). • Explain how you extract those variables from EDHS data sets. • Explain how you managed missing data, if any. • Describe the purpose of using trace plots, kernel density plots, and ACF plots. • Have you considered a design-based analysis since the DHS survey employed a complex design? Results • When you present findings, start with a text description and refer the reader to any figure or table for details. • In the result section, present only what you found, not how you found it. • First, you need to present the characteristics of your study participants. • Present the overall estimation of LBW before presenting the regional variation. • Why did you prefer to use figures instead of tables? You may better organize and present several findings shown in Fig. 1, Fig. 2, etc. • One of your findings is that the severity of LBW tends to decrease as the age of the mother increases. But is that always true among those mothers with an advanced age, which may be greater than 35 years? Have you conducted any sensitivity analyses? • Overall, the result lacks a proper and clear description of statistical outputs in non-statistical explanations. Discussion • Apart from a simple comparison of findings, discussion should entail the clinical and practical implications of the findings. • As part of the limitations of the study, you need to disclose the role of chance, bias, and confounding factors in your findings. And how do you minimize or control their effects? • Recommendations are not specific, practical, or action-oriented. (i.e., targeted public health interventions, community-based health promotion activities, etc.) Reviewer #2: Title: Bayesian Rank Likelihood-Based Estimation: An Application to Low Birth Weight in Ethiopia is a good introduction to Bayesian-based estimation. But I do have some points to be more explained - Intrauterine is the main factor that causes LBW in developing countries in literature, can you explain this about your findings or your context and provide enough justification for why would it differ in the Ethiopian context? This is important because the connection with literature is vital. - Additionally, using Bayesian estimation by itself is not enough gap to conduct research, the researchers must explore more to declare a clear gap as enough evidence on LBW is already available in Ethiopia. - Your introduction section did not reflect the fact that many studies were conducted from different perspectives, you may need to dig more to show the gap in the literature. - If you consider the Bayesian model as a novel (I reviewed many papers with Bayesian models), you need to present more methodological differences and provide enough evidence of how it is different from other traditional models to lay ground for readers - Variables in finding can be rearranged to a positive or negative association with LBW - Until in the method you did not provide evidence of source of data that is a big missing, please correct accordingly starting from abstract - The data you used is indeed from DHS 2016, isn’t this too old? There is a recent one in 2019. Or why you can not combine them to see the commutative effect or just use the recent Mini-DHS. - Methods are very limited as you said a golden approach, may need to include all method and material sections rather than present context and directly go to statistical approaches e.g. data preparation, sampling, and handling missings….generally, It is good to have a similar structure between the results and the method section. - What is the difference between Birth weights such as HBW NBW LBW VLBW ELBW and what does progress look like? (maybe in the table) because in Figure 1, I can see no difference among LBW, VLBW, and ELBW - You need improve the discussion as per the above comments - Conclusion must be more practical than tending to provide more general information. - ********** 6.

(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: (No Response) Reviewer #2: TITLE: Bayesian Rank Likelihood Based Estimation: An Application to Low Birth Weight in Ethiopia Very good title, but it still has many concerns that need serious attention. I am sorry for the delay but this manuscript may need some critical evaluation and is far from consideration for publication. My comments are presented as follows - The authors already published an article with similar findings from previous EDHS data(https://doi.org/10.5061/dryad.3j9kd51sg). This makes the reasoning for conducting the current study insufficient. What is the difference and how current recommendation show improvement from the previous one - In paragraphs 3 and 4 all the determinants factors were presented very well. Thus, if all is known about LBW, what is the importance of having the current study? - The argument of a large sample covering a larger area of the country, even the study the authors published in March 2024 is larger and covered a more area of the country. so, how did this work out for the authors without making a clear link between this and the currently published one? - Overall, the evidence on LBW is overly available already, and the current argument that because of using Bayesian Rank Likelihood Based Estimation needs to be carefully evaluated if it deserves research. The authors need to sequentially construct the flow of information including the most current evidence and show why it is important to research in the background/introduction. - For me, I can't make any difference between the published article (https://doi.org/10.5061/dryad.3j9kd51sg) and the currently under review manuscript. - It looks to me completely similar to what was published in March 2024 (same dependent variable, the same database, the same population but different articles)….how that is possible. I would retake the revision in case I get somehow wrong. ********** 7. PLOS authors have the option to publish the peer review history of their article (what does this mean?).
