Higher FBS scores indicate healthier food choices. Group I included patients with scores ≤0, representing less favorable eating behavior, and Group II included patients with scores >0, representing more favorable eating behavior.

BMI, Body Mass Index; CI, Confidence interval; FBS, Food Behavior Scale; FMF, Familial Mediterranean Fever; OR, Odds ratio.

Data are presented as mean ± standard deviation, median [interquartile range], or n (%), as appropriate. Continuous variables were compared using the independent-samples t-test or Mann–Whitney U-test, and categorical variables were compared using the Pearson chi-square or Fisher exact test. Hedges' g, rank-biserial correlation, and ORs were reported as effect-size measures for parametric continuous, nonparametric continuous, and binary categorical variables, respectively.
