Set aside: found but not counted (1)
NegatedCarcinogenicity: “13 13.1 No long-term studies evaluating the carcinogenic potential of trifluridine/tipiracil in animals have been performed. Trifluridine/tipiracil was genotoxic in a reverse”
These matched a hazard term but the text negates the finding, or names a test, a disease or a drug class rather than a finding about this drug. Shown so you can review them yourself.

For information only. This is a count of how many of the six NIOSH hazard-criteria appear in this label after negated and supporting-only statements are set aside. Findings from animal studies count, as NIOSH’s definition counts them, and are tagged “Animal data”. It is not a hazard determination, and the drug-class hint is not counted.
