Group V: Venue-recruited MSM; Group I: Internet-recruited MSM.

Multivariate OR: Odds ratio obtained from stepwise multivariate logistic regression using univariately significant variables as candidate variables.

Variable considered included all those listed in Tables 1, 2 and 3. For Group V (venue-recruited MSM), univariately significant variables included age group, number of items showing perceived discrimination against MSM, and having best friends supporting one's sexual orientation. For Group I (internet-recruited MSM), univariately significant variables included having best friends supporting one's sexual orientation, and number of friends having MSM behaviors. Only multivariately significant variables are summarized in Table 5.

*p < 0.05; **p < 0.01; ***p < 0.001.
