Diagnostic performance of antigen detection by the urine O. viverrini Excretory Secretory (OV-ES) assay compared with the gold standard formalin ethyl-acetate concentration technique (FECT) in field-collected samples (n = 235) and the odds on predicting opisthorchiasis by urinary antigen detection using urine OV-ES assay.

*AUC refers to the area under the Receiver operating characteristic (ROC) curve.

°Positive Predictive Value (PPV), Negative Predictive Value (NPV) and Likelihood Ratios (LR) were estimated using 53% prevalence rate of OV.

^†The term LR+ refers to the likelihood of observing a positive test result in patients with OV;

LR- refers to the likelihood, after subtracting from 1, of observing a negative test result with individuals without OV infection
