Results Overview

The primary outcome was screening uptake, defined as: a) the proportion of participant women with any HPV test (self-test or HPV at health centers) in the information system, in the 6 months after the CHW visit, and b) the proportion of women in the intervention group with a self-test in SITAM, in the same 6 month period.

SECONDARY outcome

Timeframe: within one year after the CHW visits

Population: Population included in the HPV self-testing group to calculate CIN2+ detection rate includes only women who were self-tested (n=2519). It excludes 99 women from this group who were not self-tested and were tested at health centers.

calculated as the percentage of women with histologically confirmed CIN2+ over total number of tested women, both for women with self-testing and those HPV tests taken at health centers.
