Faecal egg count reduction (FECR) following 253 anthelmintic treatments (sheep: 218; goats: 35) performed in 223 small ruminant flocks (sheep: 193; goats: 30), and paired comparison between anthelmintic categories. n = number of flocks using anthelmintic category; MOX = moxidectin; AV = avermectins, LEV = levamisole; MOP = monepantel; BZ = benzimidazoles; CLOS + BZ = closantel and mebendazole combination product; X²_{Kruskal-Wallis}(5) = Kruskal–Wallis chi-squared statistics with the degrees of freedom, ε²_ordinal = effect size with CI_95% = 95% confidence intervals for the effect size; n_obs = number of observations. Interpretation of ε²_ordinal = 0.16: large effect size [44]. Explanation of scientific notation for p-values: 1.05e-06 is equivalent to p < 0.001.
