Consensus Performance of the Updated OptiSafe Test using the 3 × 3 Matrix Showing Correct, Under- and Overpredictions per UN GHS Category.

UN GHS Categories Updated OptiSafe – Predicted Categories (n/N%)
Cat 1 (n) Cat 2 (n) No Cat (n)
Cat 1 (N = 48) 91.7% (44) 8.3% (4) 0.0% (0)
Cat 2 (N = 31) 64.5% (20) 35.5% (11) 0.0% (0)
No Cat (N = 47) 4.3% (2) 12.8% (6) 83.0% (39)

UN = United Nations; GHS = Globally Harmonized System of Classification and Labeling of Chemicals; Cat = Category; N = total number of GHS in vivo classified chemicals; n = total number of OptiSafe predicted GHS classified chemicals.
