Boxplots of S. haematobium log egg counts of egg-positive urine samples from Zanzibar, United Republic of Tanzania, stratified by microhaematuria grading, sex and age category. a log S. haematobium egg-counts by microhaematuria grading for female and male children. b log S. haematobium egg-counts by microhaematuria grading for female and male adults. Correlation between positive egg counts and microhaematuria grading (data pooled over both sexes): Spearman’s rho in children= 0.65, P < 0.001 (n = 39,207), Spearman’s rho in adults = 0.32; P < 0.001 (n = 18,155). In contrast to the boxplots, the correlation coefficients were calculated using egg counts from positive and negative urine samples
