Note: Descriptive statistics for dependent variables refer to the countries included in the analysis of that variable. Values for all other variables refer to the analysis of change in prevalence (N=34). The descriptive statistics are highly similar, however, regardless of the particular sample. See note at bottom of Table 2 for detailed listing of countries excluded from each sample.
