In all bivariate models, the dependent variable was lab-confirmed negative (coded 0) or positive (coded 1) rectal chlamydia or gonorrhoea result. ‘Number of male sex partners’ was the number of different men a participant reported having anal sex with in the past 3 months; ‘number of condomless anal intercourse acts‘ was the number of condomless anal intercourse acts reported in the past 3 months; ‘sexual orientation disclosure’ measured whether men were completely closeted, closeted to some or out to everyone about their sexual orientation (higher scores indicate more outness); reference category was 0, ‘completely closeted’.
M, mean.
