Note. The comparison group is “Would Not Use” (N = 1,375). Adjusted Odds Ratios (AORs) were adjusted for all other covariates. We adjusted for cohort when computing both ORs and AORs. Results from missing data indicators not presented. Weighted percentages are rounded so they do not always add up to exactly 100%. MSA = metropolitan statistical area.
