Letters in superscript (a, b, c, d, e, f, g): proportions and means with the same superscript letter statistically differ at P < 0.005 in post hoc pairwise comparisons (adjusted value for a familywise Type I error rate set at 0.05)
1Post hoc tests did not reveal any significant pairwise mean differences when adjusting the critical value of p to reflect the number of tests we performed
2 Would rather know your HIV status to make the right decisions for your own health and the health of others? Scale varying from 1 “Strongly disagree” to 7 “Strongly agree”
