“The study uses age-matched C57Bl mice as a control but does not describe a vehicle control for the antibiotic cocktail or a sham transplant for FMT.”WARNReviewer 2· 85% conf
The study uses a comparative design with mdx and wild-type mice, plus antibiotic-treated, germ-free, and FMT groups, but lacks key methodological details such as randomization, blinding, and a priori sample size calculations.

“The study compares mdx mice to age-matched C57Bl wild-type, antibiotic-treated mdx, germ-free mdx, and fecal microbiota transplant groups.”FAILReviewer 3· 95% conf
Critical design elements such as randomization, blinding, power analysis, and inclusion/exclusion criteria are not reported, making the study design insufficiently rigorous.
