  • a Net percentage gain was calculated from the percentage of mentees who demonstrated correct skills and practices at baseline and endline. Significance (p value) was computed using McNemar's test with paired proportion of mentees' with correct skills and practices at endline and baseline. Risk Ratio (RR) was computed with probabilities of mentees' skill and practice gaps at endline and baseline.
