For the knowledge, attitude and PPE wearing sections, cells represent the averaged unadjusted scores; for the “defecation” question, cells represent the proportions of people who DID defecate in the fields.

^†

For the knowledge, attitude and PPE wearing sections, cells represent score differences based on regression results; positive numbers correspond to higher scores in the intervention group. For the “defecation” question, cells represent the odds ratios (intervention group/control group) of NOT defecating in the fields.
