^bGroupings of acceptability were determined by testing for significant differences between the highest acceptability variable in each category and each subsequent variable until significance was reached. For example, “Locations” was compared to “PrEP,” then “Partner discussion,” then “HIV home testing,” with a significance difference emerging between “Locations” and “HIV home testing.” “HIV home testing” was then compared to “HIV support groups,” “Risk reduction,” and “Online physician chat,” with significance emerging with “Online physician chat.” dfs 219–223
