The multivariable logistic regression model predicting global NCI

Predictor	B (SE)	p-value	OR	95% CI
Medical burden X benzodiazepine use	0.90 (0.34)	.009	2.45	1.25–4.81
Age	0.007 (0.01)	.42	1.01	0.99–1.03
Medical burden indexa	0.09 (0.12)	.46	1.09	0.87–1.37
benzodiazepine use (vs. no benzodiazepine use)b	-2.13 (1.00)	.03	0.12	0.02–0.84

Analyses adjusted for BDI-II scores and antipsychotic medications. The age X benzodiazepine use interaction terms was not significant (B = 0.02, SE = 0.03, p = .50), so was removed from the model

^aDue to the interaction effect, this lower-order term represents the effect of medical burden index on NCI in the no benzodiazepine use reference group

^bDue to the interaction effect, this lower-order term represents the effect of benzodiazepine use on NCI when medical burden index is average
