Univariate and multivariate odds ratios (OR) and 95% confidence intervals (CI) for the composite adverse outcome variable predicted by SPMSQ errors at initial contact

Time after initial contact	n	Patients with adverse outcome (n, %)	Univariate		Multivariate/adjusteda
			OR	95% CI	OR	95% CI
1 month	250	64 (26%)	1.13	0.94–1.36	1.09	0.90–1.32
3 months	249	117 (47%)	1.34**	1.12–1.60	1.31**	1.09–1.57
6 months	245	145 (59%)	1.47***	1.20–1.80	1.45***	1.18–1.79
12 months	245	165 (67%)	1.54***	1.22–1.93	1.53***	1.20–1.94

^aThis multivariate model was adjusted for patient sex, education and body mass index (BMI) at initial contact. Age and comorbidity at initial contact were also controlled by using the score of the Charlson age-comorbidity index
