Abstract

THE development of retroperitoneal fibrosis in 27 patients using methysergide for the prevention of headache is the occasion for this report. Irving Beck, of Providence, Rhode Island, was the first to suggest a possible connection between methysergide and retroperitoneal fibrosis in July, 1961, when this condition developed in 1 of his patients, supplied with this drug by one of us. When a second patient taking methysergide for headache was similarly afflicted in November, 1962, the 2 cases were reported.1 Since then, as of October, 1965, our attention has been directed to a total of 27 patients in whom, while they . . .

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.
