↵a A total of 69 500 cases were excluded due to missing data on one or more variables in the analysis. Data presented correspond to the valid percentage of this sample with the stated characteristic (that is, denominator excludes those with missing data on that particular variable).
↵b Of excluded cases, 45 298 (65%) had no enablement score. Data presented correspond to the valid percentage of this sample with the stated characteristic (that is, denominator excludes cases with missing data on that particular variable).
