A Seven‐Day variability study of 499 patients with peripheral rheumatoid arthritis

Mainland, D.·1965·Arthritis & Rheumatism

Abstract

At eleven clinics uniform methods of measuring disease activity (duration of morning stiffness, grip strength, number of active joints, erythrocyte sedimentation rate) produced two sets of tables: (1) interpatient single‐examination differences (499 patients); (2) changes in one week (411 patients with unchanged therapy). The second set of tables provides inter alia standards for screening new drugs and a method of correcting for initial disease severity in controlled trials.

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.
