Multivariable analysis: multinomial logistic regression taking the absence of orthorexia nervosa as the reference group.

Model 1: At Risk of ON vs. Absence of ON
Variable	p	aOR	95% CI
Cognitive restraint (TFEQ-R18)	0.333	1.12	0.89–1.42
Drive for thinness (EDI)	0.011	1.17	1.04–1.32
Ineffectiveness (EDI)	0.017	0.74	0.58–0.95
Hoarding (OCI-R)	0.024	1.30	1.04–1.64
Model 2: Presence of ON vs. Absence of ON
Variable	p	aOR	95% CI
Cognitive restraint (TFEQ-R18)	0.995	0.99	0.74–1.34
Drive for thinness (EDI)	0.862	1.02	0.84–1.23
Ineffectiveness (EDI)	0.111	1.12	0.98–1.28
Hoarding (OCI-R)	0.808	0.97	0.72–1.29

ON: Orthorexia Nervosa; TFEQ-R18: Three-Factor Eating Questionnaire; EDI: Eating Disorder Inventory; OCI-R: Obsessive Compulsive Inventory—Revised. Numbers in bold indicate significant p-values. Goodness-of-fit Pearson X² = 355.03; p = 0.998; Nagelkerke Pseudo R² = 0.219. Numbers in bold indicate significant p-values.
