Predictive value of the CAST for the identification of IBH susceptible horses before first clinical signs of IBH. Percentage of clinical endpoint healthy (N = 29; blue filled column) or IBH (N = 27; column with grey squares) horses that gave a positive CAST result with a Culicoides nubeculosus (2 μg/mL); or b Simulium vittatum (10 μg/mL) extracts. T0 corresponds to the first summer when IBH was diagnosed, or in the healthy horses the last year of the follow up study. T − 1, T − 2 and T − 3 represent the summers preceding T0, and T + 1, the summer following the clinical diagnosis of IBH. *P < 0.01; ***P < 0.0001
