I participated in the study along with my former partner. IIRC, I was asked at a health check-up if I knew my partner's status, and then asked if we wanted to enroll. It just involved meeting a (very kind) doctor every 6 months, getting a finger-prick test, and completing a form with the number of occurrences of unprotected sex. We did this for at least a year, so I hope the data were eligible.
