Uptake, accuracy, safety and linkage into care over two years of promoting annual self-testing for HIV in Blantyre, Malawi: a community-based prospective study - Data Codebook
Persistent identifier
10.17037/DATA.7
Description
A set of anonymised datasets produced in a community-based study to investigate self-testing for HIV in Blantyre, Malawi. Taken together the datasets enable replication of findings from the study including estimation of uptake of HIV self-testing (HIVST), analysis of sensitivity/specificity of self-reported self-test results compared to nurse-performed finger prick testing, and investigation of self-reported coercion to self-test.
Data Codebook
This dataset is comprised of five tables - census, quality_assurance, self_completed_questionnaire, self_testing_individual_revised, and self_testing_individual_crude - made available in tab-delimited text format.
