Flow chart for group screening

For group screening, a trained medical provider was assigned as a site coordinator at each of the screening sits. The site coordinator organized the screening twice a week at the community site. With consensus of the participants in group, the site coordinator would first sign up for them on the website. After complete registrations for a group of participants, the coordinator distributed the sampling kits to each of the participants one by one. Self-collection was done by the women in a prior prepared sampling room in group (or in the preset cabinets privately) following the graphic or video instructions. The site coordinator would answer all questions from the participants but not get sample for them. At least one small cabinet was set at the site in case that any women would request for a private room for sampling. After sampling, the site coordinator collected the samples and shipped them to the testing lab
