of F&S Reviews.The Committee and Editor examined concerns related to the methodology used for the meta-analysis and determined that two flaws undermine the validity of the conclusions presented in the meta-analysis.(1) Three out of the four randomized controlled trials incorporated in the analysis were, in fact, the same single study at different stages, which resulted in the same patients being counted multiple times.This was verified by Dr. Ruiz, an author of these publications.(2) Cohort studies with different designs and comparisons were pooled inappropriately.The Journal regrets that these flaws were not detected during peer review.
