P	--^a	0.40	0.51	0.02

NOTE. Data are no. (%) of participants unless otherwise noted. P value represents comparison between intervention group and control. Participants were analyzed by the arm to which they were assigned. Abbreviations: RR, relative risk; ARR, absolute risk reduction; CI, confidence interval.

“Personal and Household Hygiene Education Only” was used as the comparator group to determine RR, ARR, and P values.
