A. A Spearman's correlation coefficient of 0.616 (P<0.0001) was found for a comparison considering all 206 samples. B. Considering positive and negative samples for the Kato-Katz technique and the Schistosoma PCR-ELISA system, a Spearman's correlation coefficient of 0.700 (P<0.0001) was observed. The continuous line represents the linear regression, and the hatched line represents the 95% CI.
