A, ANN probabilities for clastogen classification are graphed for each of 103 chemicals that were evaluated in TK6 cells with the MultiFlow DNA Damage assay. Chemicals are grouped according to class: A, adequately tested; I, inadequately tested; S, top concentration limited by solubility. A series of probabilities are plotted for each chemical, with each point representing a different concentration. A dashed line indicates the threshold value that probability scores had to reach in order to be considered significant.
