The DNTP Technical Report (TR) Level of Evidence Criteria are available here: https://ntp.niehs.nih.gov/go/baresults. In the table below this information is further delineated into three fields:

Level of Evidence: The overall category of evidence of carcinogenic activity for the TR, Species, Strain and Sex
Organ Site Call: The level of evidence supported by the specific organ site for the TR, Species, Strain and Sex. When the Organ Site Call directly supports the TR Level Of Evidence the Finding Type flag is set to “Neoplastic Lesion”. Some Organ Site Calls could support a separate call of Equivocal Evidence; this is noted in Finding Type by the flag “May Have Been Related”
Finding Type: Further identification of the Organ Site Call. Where this says “Neoplastic Lesion” the Organ Site Call supports the TR Level of Evidence and the Organ Site Call is the same as that of the TR. Where Finding Type says “May Have Been Related” the TR Level of Evidence for other responses led to an overall call of Clear or Some Evidence but the specified organ supports a call of Equivocal Evidence.
