Chemicals with in vivo experimental acute oral toxicity data used for the additional predictivity analysis.

Modeled end point	Total number of chemicals in curated data set
VT	1,296
NT	1,153
EPA categories	1,089
GHS categories	1,083
$\mathrm{L}{\mathrm{D}}_{50}$ value	916

Note: The number of chemicals represents the total for that data set, not the number that fell beneath the threshold (e.g. for Very Toxic). See Supplemental Material 8. EPA, U.S. Environmental Protection Agency; GHS, U.N. Globally Harmonized System of Classification and Labeling of Chemicals; $\mathrm{L}{\mathrm{D}}_{50}$, dose of a substance that would be expected to kill half the animals in a test group; NT, nontoxic/toxic; VT, very toxic/not very toxic.
