AOR Adjusted odds ratio in multivariate logistic regression, ORm Adjusted odds ratio in multiple forward stepwise regression
AOR and ORm were calculated after adjusting for confounders, and confounders including age (as a continuous variable), marital status (currently married or not), Guangzhou permanent resident (Yes or No), education level (higher than post-secondary education level or not), sexual orientation (bisexual/uncertain, or homosexual), and duration being MSM (less than five years, five years/ longer than five years), recruitment via Internet (Yes or No)
n1: n1 actually is the n in Table 3, to distinguish the n in Tables 4, 5, 6, we use n1 to represent the n of Table 3
NS Variables with p < 0.10 in multivariate logistic regression, but were not significant in multiple forward stepwise logistic regression
