aAnalyzed using Pearson’s Chi-square test for categorical variables or ANOVA for continuous variables, unless noted differently. b Due to small cell count, analyzed using Fischer’s Exact test. c Data missing for 28 patients (for AN: n = 12, for Atypical AN: n = 11, and for ARFID: n = 5). Race/Ethnicity excludes patients who declined to respond or selected “other” (n = 7). */**/*** Denotes significance between eating disorder groups using pairwise comparisons (p < .05)
