Baseline and primary data for the partner-provided HIV self-testing and linkage (PASTAL) adaptive multi-arm multi-stage cluster randomized trial in Blantyre, Malawi – Data codebook

Persistent identifier

10.17037/DATA.00000923

Description

Dataset containing details of 2,349 pregnant women accessing antenatal care in three primary health centres in urban Blantyre, Malawi who gave informed consent to participate in an adaptive multi-arm multi-stage cluster randomized trial. The unit of randomization was the antenatal care (ANC) clinic day. On a given ANC day, women could receive standard of care (SOC) of receiving just an invitation letter to deliver to their male partner who was absent at this ANC visit. Or, the women could receive SOC plus two oral self-test kits alone or in combination with a guaranteed financial incentive of $3 or $10 conditional on clinic attendance following self-testing for HIV care or prevention. Two other arms offered a lottery-based incentive with 10% chance of winning $30 to male partners achieving the primary outcome, or a phone call reminder to the male partner immediately following collection of kits by the woman repeated after five days. The dataset contains variables on baseline data for the women and their male partners as reported by the woman as well as data underlying the trial outcomes by arm. Recruitment and follow-up were completed between 8 August 2016 and 30 June 2017.
