Explanatory variable	Univariable model	P value	Multivariable model*	P value
	OR (95% CI)		OR (95% CI)
Age (years)	1.04 (1.01 to 1.08)	<0.01	1.04 (1.00 to 1.07)	0.05
Females (vs males)	1.41 (0.93 to 2.14)	0.11	1.63 (1.04 to 2.57)	0.04
Multimorbidity†	3.04 (1.99 to 4.65)	<0.01	4.01 (2.43 to 6.63)	<0.01
Polypharmacy‡	1.30 (0.86 to 1.96)	0.21	0.69 (0.42 to 1.14)	0.144
