  1. aCI denotes confidence interval. Proportions estimated using complex survey designs. Differences calculated using t-distribution for differences with specified degrees of freedom. Test statistic for distribution uses Pearson’s chi-square test converted to an F-statistic for the survey design with the second-order correction of Rao and Scott with specified degrees of freedom [46]
