Fig 1. Differences in knowledge, attitudes and practices (KAPs) for surveys conducted 1 month before (baseline) versus 3 and 12 months after (first and second follow-up) an oral cholera vaccination campaign in Maela Camp, 2013.

Absolute differences in proportions for KAP responses in the first and second follow-up surveys compared to baseline were calculated; error bars depict 95% Wald asymptotic confidence interval (CI). Statistically significant differences (CI not overlapping zero) are shown in grey; non-significant differences are shown in white. Outcomes marked with * have directionality of difference switched from Tables 3 and 4, so that improvements are depicted in positive direction, and negative changes are depicted in negative direction.
