Table 2. Bayesian parameters determining the effect of different concentrations (µg/kg) of ivermectin (IVM) on fecal egg count reduction (%), uncertainty intervals (UI), lower confidence interval (LCI)/highest posterior density (HPD), and kappa values between untreated and treated horses five weeks post-treatment (w5pt) in Thoroughbred yearlings.
