Table 2 Improvement in hepatosplenomegaly stratified by level of exposure to malaria and S. mansoni. Sectors are identified by letter and are described in the text. N i – number of children in each sector with improved organomegaly at the 3 year follow up; N t – total number of children examined at the third year follow-up; Z-Wilcoxon Rank analysis Z score indicating whether or not there was a decrease in the degree of organ enlargement between baseline and the 3 year follow up. A negative Z value and a corresponding p value of <0.05 indicates a significant decrease in organ sizes within a given sector.
