Infection intensity in relation to 'weighed' duration and frequency of water contact. Similar as Figure 5, but then adjusted for body surface and time of day (reflecting cercarial density), as previously described by Scott et al. . As compared to the unadjusted model (Figure 5), the residual variance (unexplained variation) of the adjusted model reduced by 41% (duration) and 54% (frequency) pre-control, and 44% (duration) and 46% (frequency) one year after treatment, respectively.
