From: A prospective study on insect bite hypersensitivity in horses exported from Iceland into Switzerland
Longitudinal study of horses imported from Iceland to Switzerland. Percentage of clinical endpoint healthy (H, filled blue columns) or insect bite hypersensitivity (IBH, columns with grey squares) horses with a positive test result in the CAST with a Culicoides nubeculosus extract (2 μg/mL) or b Simulium vittatum extract (10 μg/mL), in Iceland before export to Switzerland (TIceland) and one to four (T1–T4) summers after importation from Iceland into Switzerland. The number of horses tested in the CAST at the different times is given in Table 2. *P < 0.05; **0.05 > P < 0.01; ***P < 0.001
