NOTE. Data are expressed as N (%) or proportion unless otherwise noted. P value represents comparison between intervention group and control. Participants were analyzed by the arm to which they were assigned. Abbreviations: SSTI, skin or soft tissue infection; RR, relative risk; ARR, absolute risk reduction; CI, confidence interval.
a
“Personal and Household Hygiene Education Only” was used as the comparator group to determine RR, ARR, and P values.
