Other than the difference in wasting prevalence, for which the P value was close to the level of significance ( P = 0.053), there were no significant differences between cohorts in the morbidity markers that we measured at year 1 ( Table 2 ).
However, in the parent study that consisted of 25 villages each receiving annual CWT or biennial SBT from which the six villages in each cohort were a subset, there were no statistically significant differences in the final prevalence or intensities of infection between these two treatment regimens, although there were highly significant reductions in prevalence and intensity of schistosome infections over time for each treatment strategy (manuscript in preparation).
