Participants were self-selected into intervention or control group based on the clinic in which they sought service. Participants were not blinded nor explicitly told which treatment group they were in, but may have been able to ascertain their treatment group based on the study description and services received. Female clients presenting at the clinic were asked by the receptionist if they were interested in participating in a “women’s health study”. Those interested were escorted by a trained research assistant to a private room in the clinic where they received information about the study, were screened for eligibility, and, if eligible and interested, completed written informed consent prior to baseline data collection. Women were eligible to participate in the study if they were “interested in receiving family planning services” at one of the six FHOK study clinics and self-reported being female, between the ages of 15-49, not currently pregnant or sterilised, having a male partner with whom they had sex in the past three months, no plans to move out of the area for the next six months, having a mobile phone safe for re-contacting for follow-up surveys, and being able to participate in a private interview. Because two trial facilities were previously pilot facilities, women who reported having taken a health survey in the past three months were excluded. Surveys were administered by research assistants using tablet computers in English or Kiswahili based on the participants’ preferences. Participants completed surveys at all time points at the clinic of enrolment. In a few cases, follow-up interviews were completed over the phone for those unable to return to the clinic. Patients were enrolled from July to December 2018 and follow-up from October 2018 to June 2019. The trial was stopped in June 2019 after the sample size was met and follow-up completed (ARCHES cluster-controlled trial consort flow chart (Nairobi, Kenya; 2019)Notes: *Participants were contacted at the 6-month follow-up point irrespective of their participation in the 3-month follow-up, unless they had specifically declined further study participation. **Numbers at exit reflect those included in the analytical sample via the modified ITT approach
