CCA G-score results: a number of PSAC with each G-score and b correlation between G-score and epg. A Frequency histogram of CCA G-scores shows the number of PSAC with each G-score. A child with a score of G1 was considered not-infected, and scores G2-10 were considered to be infected with Schistosoma mansoni. B Scatter plot of epg values against CCA G-score values, with linear regression line shown. The linear regression model estimated, that in this cohort, for every increase in G-score by a value of one, the epg increased by 20.4 (6.50–34.4, P = 0.006).
