  • *Sample size of FSW attended in the specific year.

  • †The sexual behaviour questionnaire was not fully implemented in 2005.

  • ‡Adjusted proportion (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).

  • FSW, female sex workers.
