Within-test variability of the mean CO scores calculated over the reading times at 24, 48, and 72 h. Proportion of animals within each CO^Maj group

Proportions that fall in the light-grey area (No Cat range) correspond to animals with mean CO < 1 that were tested with chemicals with CO^Maj < 1; Proportions that fall in the grey area (Cat 2 range) correspond to animals with 1 ≤ mean CO < 3 that were tested with chemicals with 1 ≤ CO^Maj < 3; Proportions that fall in the dark-grey area (Cat 1 range) correspond to animals with mean CO ≥ 3 that were tested with chemicals with CO^Maj ≥ 3; Proportions in bold (diagonal) correspond to animals with mean CO scores equal to the CO^Maj of the chemicals tested in those animals
