Patient selection
Two hundred and eighty five caregiver-child dyads were recruited for the HADITHI trial from eight facilities in Eldoret, Kenya between June and August 2013. We restricted our analysis to children who were not disclosed to at baseline. Disclosure was defined as a binary variable (whether or not the child knew his/her HIV status) as reported by either child or caregiver via disclosure questionnaires. Of the 285 caregiver-child dyads, 146 children (51.2%) were non-disclosed at baseline by either caregiver or child report.
