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: General comments The authors conducted a systematic review and meta-analysis study to assess risk factors in drug resistant juvenile myoclonic epilepsy. The results were interesting and valuable for clinicians. However, I have some concerns that should be addressed regarding the methodology and interpretation of results. Specific comments - In Line 131, I am not familiar with The SysRev- Sysrev- JME- web-based platform. Does it act like a reviewer instead of a human? If so, please mention the validity and accuracy of using it for systematic reviews. If it is not accurate, then methods to compensate for accuracy should also be done. - In Line 132, “one reviewer” collected the article. In the screening process, independent two reviewers should blindly review articles. Did the authors independently and blindly review the articles? - What is the definition of JME (e.g., age, semiology, EEG, etc.)? Is it based on the 2022 ILAE criteria or on the definition of each study? - In Line 194, did the authors extract the data only from SysRev- Sysrev- JME- web-based platform and Tabula? These systems may miss some data. How did the authors manage missing data due to these systems? - In Line 210, Cochrane's ROB evaluation tool is designed for randomized controlled trials, but the authors applied it to non-RCT trials. This is not appropriate. The authors should use a Risk of Bias tool designed for each type of study. Also, all studies had a low risk of randomization, but this seems incorrect as it may include non-RCT articles. - In Line 279, please insert the citation for included 25 studies. - In Line 294, the prevalence of refractory JME has sampling bias because the searching strategy include (”Drug refractoriness” OR ”Predictors of drug resistance”). The prevalence might be higher than general population and are likely to mislead the readers. It would be better to exclude the prevalence in the results and conclusion. Reviewer #2: This is a systematic review and meta-analysis investigating factors associated with drug-refractory JME. The authors found that psychiatric disorders, febrile seizures, alcohol consumption, aura, history of CAE, having three seizure types, and focal EEG abnormalities are the factors related to drug refractoriness in JME. These findings may be useful for predicting drug response and prognosis when managing patients with this condition. However, I have several concerns regarding the methodology of this study. Major comments Comment 1 The authors stated, “The keywords used during the search included: (”Juvenile myoclonic seizures” OR ”Myoclonic epilepsy”) AND (“Risk Factors” OR ”Socio-demographic predictors” OR ”Clinical predictors” OR ”Electrophysiological predictors”) AND (”Drug refractoriness” OR ”Predictors of drug resistance”)” in line 134. It seems that some of those keywords were too specific. Did the authors use thesaurus or MeSH headings? As a matter of fact, I found only “1” article when I put the identical search string above in Pubmed, although the authors stated they found 792 articles in Pubmed/MEDLINE according to Figure 1. Authors should clarify the exact search string they used in this study. Comment 2 The authors stated, “The meta-analysis showed that 33.28% (95% confidence interval (Cl)) of individual with JME were refractory to drugs.” in line 294. In this sentence, the number of 95% CI was lacking. Additionally, the absence of consideration for heterogeneity among the included studies raises concerns about the robustness of the meta-analysis. As a matter of fact, when I calculate the rate of the sum of “DRE” to that of “Size” in Table 3, the answer was “0.33278…”, which was identical to the percentage of DRE in this article. If the authors simply merged the results without weighting, it should not be accepted as meta-analysis. Authors should describe the model they used to merge the results, and include the figure of forest plot. Comment 3 Table 2 is the list of included studies. Each article in this table should have reference number. Furthermore, some of the articles in this table were not found in the Reference (for example, an article by Hirano et al.). Such error is critical for systematic reviews and meta-analyses and the authors should have been more cautious. Comment 4 The Discussion section is lacking proper compartmentalization. It needs a restructuring. It can be divided into several paragraphs, for example: 1. The summary of the findings, 2. Discussion about DRE incidence, 3. DRE-associated factors in demographic domains, 4. Clinical domains, 5. Electrophysiological domains, 6. Significance of the study, 7. Limitation of the study. Minor comments Comment 1 The authors used several outdated terms such as “primary generalized, partial, and secondary generalized” in line 60; anti-epileptic drugs and AEDs in the whole manuscript. The use of generalized onset, focal onset, focal to bilateral tonic-clonic, anti-seizure medication, and ASMs are preferred, respectively. (Please see the ILAE 2017 classification of seizure types and the position paper by the nomenclature task force of ILAE in 2022.) Comment 2 The authors stated that JME has an underlying developmental disorder and multiple brin regions are affected by citing the article by Iqbal et al (ref 7). This cited article represents their preliminary results and they published more concrete study in Epilepsia thereafter. Comment 3 The authors stated, “many JME patients show impairments to AEDs, and this can affect the development and maintenance of refractory JME” in line 96. I would like the authors elaborate on what “impairments” was. It was not sure if they are trying to refer to the low adherence to ASMs among JME patients or adverse effects that JME patients may experience. Comment 4 Table 1 is describing the difference of each ASM and it is concise and informative. However, it does not appear to have much to do with the main subject of this article. I think this table is not necessary. Also, if the authors would like to include this table in the article, proper referencing is needed. Comment 5 The authors stated, “On the other hand, relief of myoclonus after approximately 40 years is unreasonably noted in most patients.” in line 84. I didn’t understand exactly what this sentence means. Please consider paraphrasing. Comment 6 The authors stated, “Low levels of education were linked to resistant epilepsy (p=0.08, OR=4.99), which is explained by “health literacy” in line 361. However, this is not significant because P value was exceeding 0.05 and 95% CI was wide. ********** 6.

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: Although the authors mentioned about Newcastle-Ottawa scale (NOS) for risk of bias assessments, they used Cochrane’s ROB and did not use NOS. It is not appropriate. Please use risk of bias assessment tools for non-randomized study such as NOS or JBI critical appraisal tools. Reviewer #2: Thank you for submitting the revised manuscript. I think it is well revised based on the reviewers’ comments and I appreciate their effort. Below are some observations and suggestions: Line 38 While the term "95%CI" is mentioned in the abstract, the actual range of 95% confidence intervals for each odds ratio is not provided. Additionally, for clarity, it is recommended to spell out "OR" and "CI" when they first appear in the abstract. Line 70 The authors introduced the term "idiopathic generalized epilepsy" at line 70. Considering the apparent similarity between GGE and IGE within the manuscript's context, it is advisable to consistently use one of these terms throughout. Line 72 GGE is spelled out repeatedly. GGE is already defined previously. Line 93,137 and 369 JME is spelled out repeatedly. Line 188 There may be a typographical error, and "seizure-resistant" could potentially be corrected to "drug-resistant" to better align with the natural context. Line 199 It is suggested to maintain consistency by adhering to the abbreviation "VPA" for valproic acid, as previously defined. Figure 6 is interesting. It seems that the regression curve is showing upward trend. Is there possibility that the prevalence of DRE among JME is increasing over the years? In table 4, P values should be described as they are instead of “<0.05”. They can be written as like “<0.001” only when they are much smaller than 0.05. ********** 7.
