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
EAT total score	0.13	0.34	< 0.001	0.10–0.16
DERS non-acceptance	0.16	0.10	0.032	0.01–0.30
