Doctors and Drug Companies
Abstract
In this article, Blumenthal describes the nature of current relationships between doctors and the pharmaceutical industry. The report analyzes how financial relationships — which may involve gifts, free meals, consulting fees, or lecture honoraria — influence physicians' prescribing decisions and how the relationships between physicians and drug companies are likely to change in the future.

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.
