  1. p < 0.10, *p < 0.05, **p < 0.01
  2. AOR Adjusted odds ratio in multivariate logistic regression, OR m Adjusted odds ratio in multiple forward stepwise regression
  3. 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)
  4. 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
  5. NS: Variables with p < 0.10 in multivariate logistic regression, but were not significant in multiple forward stepwise logistic regression
