  • STI, Sexually transmitted infection; VD/LAP, vaginal discharge or lower abdominal pain.

  • *Modified Poisson regressions adjust for health worker profession (nurse, nurse midwife or medical officer), follow-up visit, patient gender, syndromes, observation by a clinical specialist and before coming to the clinic whether or not the patient understood that s/he had the right to refuse an HIV test. †Results with a p value less than 0.05 are highlighted in bold.
