Model adjusted for other covariates described in step 6 in Table 2.
†
Data for age and sex come from prebalanced data set (N=5,139). Adjusted odds ratio (OR) comes from model adjusted for other covariates described in step 6 in Table 2 plus age and sex. Data for other covariates come from postmatched cohort (N=1,590).
