Multivariable analysis: hierarchical linear regression taking the ORTO-R score as the dependent variable

Variable	UB	SB	p	95% CI
Model 1 taking the EAT score as an independent variable
EAT total score	0.15	0.39	< 0.001	0.13–0.18
Model 2 taking DERS-16 and EAT total scores as independent variables
DERS total score	0.06	0.17	< 0.001	0.03–0.08
EAT total score	0.13	0.33	< 0.001	0.10–0.16

Nagelkerke R² values: Model 1 = 15.1%; Model 2 = 17.7%; numbers in bold indicate significant p values

UB unstandardized beta, SB standardized beta, CI confidence interval, EAT eating attitude test, DERS difficulty in Emotion Regulation Scale
