  • Values in bold were significant (p<0.05); due to rounding into 1 decimal, 1.0 is not always significant.

  • Regression analysis corrected for the number of consultations.

  • MSM, men who have sex with men; ref, reference; SES, socioeconomic status; STI, sexually transmitted infection; NT, not tested in multivariate model, since p>0.20 in univariate analysis.
