Estimate of the mean procedure times with 95% confidence intervals for ASHAs npB1, npM1, and npL1 over successive procedures performed (for the duration of the pilot study). ASHA npM1 has the narrowest CI and least estimated mean procedure time while npL1 has the widest CI and highest estimated mean procedure time at end of the study. The estimate of 95% CI and mean procedure time was obtained using a bootstrapped sample that included risk assessments performed up until and including that time period in the study. This was performed to account for uneven sampling bias (for example, at the 5th procedure, procedure 1 till 5 were taken as samples and bootstrapped). After ASHA npL1’s 13th procedure, her estimated mean procedure time increases which suggests that she took much longer to complete the last two risk assessment procedures.
