Decision values (DV) based on GARD®skin predictions. Chemicals were classified as skin sensitizers (red symbols) when the mean of the support vector machine DV for triplicate samples was > 0. Cells were treated with 75 µM PPD, 6.5 µM BEN, 500 µM POL, and 220 µM NND. Mean with standard deviation is shown.
