  • a Net percentage gain was calculated from the percentage of mentees who answered correctly the knowledge questions at baseline and endline. Significance (P value) was computed using McNemar's test with paired proportion of mentees' with correct knowledge on the topics at endline and baseline. Risk ratio was computed with probabilities of mentees' knowledge gap on the topics at endline and baseline.
