Data are mean (SD) or% (SE).
1
Follow-up values are averaged over all of the follow-up rounds.
2
P-value comparing intervention arm to control arm, accounting for baseline values, the stratified randomization, and the clustering in the study design.
3
Denominator is “% of pupils that used a latrine,” as shown above.
