Table showing mean percentages of faecal egg count reduction after treatment with fenbendazole (FBZ), pyrantel (PYR), ivermectin (IVM) and moxidectin (MOX) evaluated against cyathostomins in a total of 102 horse yards located in Germany, Italy and UK. The faecal egg count reductions (%) and respective 95% confidence intervals (CI) (set between 0 and 100%) were calculated using the Bootstreat programme using the formula FECR = 100 * (1 - arithmetic mean of FEC post treatment/arithmetic mean of FEC per treatment) with 2000 repeats. H: treated horses in each yard; G: number of horses in each treatment group.
