<qa>  What is the endpoint of screening completion defined as?This 2-arm randomized control trial of 510 women will investigate whether offering HPV testing by mailed at-home self-collection to under-screened women increases their likelihood of completing cervical cancer screening. All participants will received a screening invitation by phone: a phone call providing i education on cervical cancer, and ii assistance scheduling an appointment for free screening at a study-affiliated clinic, if needed. Those randomized to the intervention arm will first be mailed a kit to self-collect a cervico-vaginal sample, return the sample for oncogenic HPV testing, and receive their results by phone. HPV negative women will be considered screening complete. HPV positive women will be invited to schedule an appointment for free follow-up in-clinic screening in the same call in which their results are delivered. The study endpoint of screening completion will be defined as completing in-clinic screening control arm participants and HPV positive intervention arm participants or receiving a negative HPV self-collection result intervention arm.
