A Comparison of the Sensitivity and Fecal Egg Counts of the McMaster Egg Counting and Kato-Katz Thick Smear Methods for Soil-Transmitted Helminths
Figure 5
The absolute bias for McMaster and Kato-Katz in the assessment of drug efficacy.
The bias (i.e., absolute value of the differences between the ‘true’ drug efficacy (TDE) and the observed fecal egg count reduction) for McMaster and Kato-Katz across the different trials (countries), pre-drug administration fecal egg counts (pre-DA FEC) and ‘true’ drug efficacies (TDE) based on predictions from statistical models.
