Faecal egg count reduction (FECR) estimates with 90% credibility intervals (CrIs) for fenbendazole (FBZ), ivermectin (IVM) and moxidectin (MOX) for Nematodirus spp. Using the eggCounts (EC) and bayescount (delta method, BC-D) R packages, the 90% CrIs were calculated. While the eggCounts package also provides an estimate for the FECR, the bayescount package only provides the CrI. Therefore, the FECR was calculated simply from mean pre and post egg counts. For sheep, the grey zone is located between 95% and 99% FECR and indicated by vertical lines. Colours indicate susceptible (green) and resistant (red) results. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
