Abbreviations and definitions: Fasciola_PP, smoothed square root of F. hepatica percentage positive ELISA value; NN_BTB, nearest neighbour’s smoothed BTB probability; HerdSize, square root of herd size; NDVI, normalised difference vegetation index is a measure of vegetation greenness; SqrtMOff, square root of movements off farm; MeanT, mean temperature (°C); VPD, Vapour Pressure Deficit is a measure of lack of moisture equilibrium between an object and the atmosphere, the higher the VPD, the more rapid the rate of desiccation; TVar, temperature variance, indicates the magnitude of the seasonality, i.e. larger values indicate larger differences between winter and summer extremes; OR, odds ratio; L/U 95% CI, lower and upper 95% confidence intervals of OR.
