↵* The sample sizes were unweighted, but the percentages were generated as weighted estimates.
↵† Unweighted N and weighted % represent the breakdown of the entire study population. Subsequent columns represent the percentage of people who donated blood during the indicated time period.
↵‡ Wald χ2 tests were used to determine changes in the prevalence of recent blood donations for each subgroup. The values in bold are significant.
