Column 3 is color coded as to “a priori Genotox Expectation”, where aneugen = blue, clastogen = yellow, non-genotoxicant = white, and likely ≥ 1 MoA = green.

Columns 4+ are color coded as to Machine Learning and Global Evaluation Factor predictions, where aneugen = blue, clastogen = yellow, non-genotoxicant = white, and likely ≥ 1 MoA = green.
