Describing the validity of carcinogen screening tests
Open accessAbstract
SEVERAL issues pertinent to the validation of screening tests and to the evaluation of screening programmes have evolved, largely in the epidemiological and general medical literature (Vecchio, 1966; Holland, 1974; Henderson, 1976). For this reason, laboratory scientists interested in the development and validation of carcinogen screening tests may not be fully aware of some useful concepts. The paper reviews several such concepts and their relationships. These relationships explain, for example, why the "predictive value", although frequently used as an index of the utility of a screening test, is not well suited for that purpose. A carcinogen screening test is usually evaluated by applying it to a group of substances, each of which is considered to be, or not to be, a carcinogen according to some selected criteria (i.e. animal or human carcinogenesis). The specific criteria chosen are beyond the scope of this discussion; however, the validity measures of a screening test are meaningful only in the context of these criteria. After some number, N, of substances has been tested, the results may be described using the format of the Table. (Terms used to describe screening tests and screening programmes are defined below the Table.) A screening test is expected to designate carcinogens as "positive" and to designate non-carcinogens as "negative". Each of these 2 distinct functions has its own measure of validity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
