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. Additional Editor Comments : Summary Report: - This retrospective study investigates risk factors for hypoglycemia in otherwise healthy children admitted with acute vomiting and dehydration. Among 560 patients aged 29 days to 17.9 years, 30.5% developed hypoglycemia (≤3.3 mmol/L), predominantly in the 2–7 year age range. Besides known contributors such as decreased oral intake and dehydration, the study identifies low BMI, low BMI-SDS, and diarrheas' as independent predictors. The findings offer a plausible mechanistic link between physiologically low BMI in early childhood and heightened susceptibility to hypoglycemia. No description of the study hospital Comments 1. The manuscript is generally clear, but occasional grammatical issues should be corrected (e.g., “IKT” should be “IKH”; “polystigmatisation” may be unclear in English and should be defined or replaced). Some sentences are overly long; breaking them into shorter units would improve readability. 2. Ensure consistent use of terms (e.g., “hypoglycaemia ≤ 3.3 mmol/L” vs. “hypoglycaemia < 3.3 mmol/L”). 3. Define all abbreviations at first use (e.g., AG for anion gap, SDS, IKH). 4. Originality and Significance: - The link between BMI and hypoglycemia is interesting and clinically relevant, especially since the 2–7 year age window coincides with physiologic BMI nadir. This provides a valuable explanatory model for age-related vulnerability. However, the claim of novelty could be better contextualized with more detailed comparison to prior studies (e.g., Daly et al., other hypoglycaemia risk factor cohorts). Consider expanding the Introduction/Discussion to highlight how your findings go beyond known associations. 5. There is a poor description of the National Institute for Children’s Diseases in Bratislava 6. Study Design and Limitations - The retrospective design is acknowledged, but the discussion should more explicitly cover potential biases (e.g., incomplete anthropometric data, reliance on medical record accuracy, confounding by underlying undiagnosed conditions). - Exclusion criteria are well defined, but it would be helpful to clarify how “healthy” was determined—particularly whether all metabolic/hormonal disorders were actively ruled out or assumed absent unless clinically apparent. 7. Statistical Analysis - Logistic regression appears appropriate; however, it is not clear whether potential collinearity between BMI and BMI-SDS was formally assessed prior to including both variables in the model. - Additional methodological details are needed—specifically, how missing BMI data were managed and whether any sensitivity analyses were performed. Providing this information would enhance transparency. - Finally, although numerous p-values are reported, no adjustment for multiple comparisons is mentioned. The rationale for the chosen approach should be clearly justified. 8. Discussion - No continuation of the line numbering. - The Discussion could better differentiate between association and causality. For example, it is unclear whether low BMI is a causal risk factor for hypoglycaemia or merely a proxy for age-related physiology. - The finding that diarrheas' was associated with increased hypoglycaemia risk is intriguing but underexplored—possible mechanisms (fluid/electrolyte shifts, increased energy expenditure) should be discussed. 9. Figures and Tables - Figures 2 and 3 are not visible and have no title in the main text. - Some legends need clarification (e.g., specify “CI” in figure legends for non-specialist readers).

Below are a few suggestions for the authors: 1) In the abstract it should be specified that this is a retrospective and single centre study. 2) In the abstract the result section could include ORs for the main preditors (BMI, diarrhoea and dehydration) 3) Line 41-42 could better read as (to avoid causal tone): Low BMI, low BMI-SDS and diarrhoea were associated with increased odds of hypoglycaemia. 4) In the introduction, could the authors differentiate between IKH and hypoglycaemia secondary to acute illness, they are overlapping but distinct entities. 5) Could the authors clarify why BMI was hypothesized as a potential risk factor? (what is the underlying pathophysiological reason) 6) In the methods section, could you elaborate further on the description of the forward stepwise selection and transformation of non-normal data? Were covariates checked for collinearity? 7) The BMI reference source used (Czech norms) may not represent Slovak chidren, could the authors justify the use of this reference? 8) For ethics consideration, please clarify that the informed consent was waived due to retrospective anonymized data. 9) For result section: the authors could split table 1 into 2 separate tables, anthropometric vs. biochemical to make it less overloaded 10) For the regression models, could the authors include odds ratios (ORs) with 95% CI ? 11) In the discussion, the speculation of low BMI being associated to smaller liver/muscle should be rephrased cautiously or deleted to avoid implying causality 12) Could the authors clarify the finding that diarrhoea is protective? Could this reflect late presentation, different dehydration mechanisms or measurement bias? 13) Regarding the age effects, although BMI correlated with age, the lack of an independent age effect in regression needs clarification; is there possibility of collinearity? 14) In the limitations: authors should discuss a) selection bias (how referral admission bias may inflate hypoglycaemia prevalence?), b) missing data (extent of missing data and how these were handled). 15) the section "Implications for clinical practice" currently reads as though the identified factors are definite predictors of hypoglycaemia, implying predictive certainty in clinical setting. However the study is a retrospective observational so it can only establish associations not causal relationships. So your findings are not yet validated as screening criteria or diagnostic predictors. So you could rephrase for example like this: Low BMI and abscence of diarrhoea were associated with increased odds of hypoglycaemia. These factors, readily indentifiable at presentation, may support early glucose screening in children with vomiting and dehydration. However, prospective validation is required before their use as predictive tools. ********** what does this mean? ). If published, this will include your full peer review and any attached files.
