RR: Relative risk (95% CI); * P <0.05; **P <0.01.
Crude RR: Relative risk of univariate analysis.
Adjusted RR: Basic demographic characteristics (i.e., age, gender) and variables that were associated with willingness to accept free HIV testing in univariate analysis among urban residents at the 0.10 significance level were put stepwise in a multivariate log binomial regression model.
