Multivariable model to assess association between a positive rapid test for syphilis and method used to sample female sex workers
| Model | Variables included | Prevalence difference | 95% CI | Prevalence ratio | 95% CI |
|---|---|---|---|---|---|
| 1 | Method | 16.8 | 3.5 to 30.0 | 3.3 | 1.5 to 7.2 |
| 2 | Method, age | 16.7 | 3.6 to 29.7 | 3.3 | 1.5 to 7.2 |
| 3 | Method, age, urban district/county | 10.2 | 4.0 to 16.3 | 2.2 | 1.2 to 3.9 |
Prevalence difference refers to the absolute difference in positive rapid syphilis test between Priorities for Local AIDS Control Efforts and respondent-driven sampling (RDS). Weights for RDS respondents are from RDS-II estimation procedure.
