Part XVI. Evaluation of the safety of new drugs by means of tests in animals

Litchfield, John T.·1962·Clinical Pharmacology & Therapeutics

Abstract

The manner in which new drugs are studied has changed drastically during the past 30 years. Certainly, the effective administration of the Food, Drug and Cosmetic Act has been a factor in this, but the importance of the gain in our basic knowledge of drug actions and the effect of intense competition in the pharmaceutic field have also played important roles. Safety evaluation has almost reached the status of a separate specialty.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lichtfield examined 6 drugs studied in animal models and found that rats and dogs demonstrated PPVs for human response of 0.49 and 0.55, respectively, essentially random chance.

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.
