Nyamuryekung'e 1997.

Methods	Cluster randomised trial.
Participants	Seven truck stops with peer health educations and associated health facilities.
Interventions	Aim: to evaluate different approaches of delivering STI services to increase utilisation by women at truck stops.

Special STI services outside normal working hours (one at fixed location, one at site chosen by women); Group 2. STI services through normal clinics, in normal working hours (integrated). Group 3. Special team of clinicians visits every 3 months. Drugs were supplied to all three groups.
Outcomes	1. Utilisation, from attendances/population. 2. Referrals who attended clinic. 3. User satisfaction. 4. Cost per patient treated.
Notes	Study undertaken in Tanzania between July 1993 and May 1994.
