  • *Sample size of clinical attendees in the specific year

  • †Adjusted prevalence ratio (APR) test for trend with 95% CI using a Poisson binomial model with year as an ordered categorical variable adjusted for sociodemographic variables with a p value <0.2 in the univariate test (age, sex, STI clinic origin, having a regular partner, country of birth, education and marital status).

  • ‡For MSM and HRH, data from STI outcomes was not fully implemented in 2005–2006.

  • §Not applicable due to sample size limitations.

  • FSW, female sex workers; HRH, high-risk heterosexuals; MSM, men who have sex with men; STI, sexually transmitted infections.
