Detection of tumor necrosis factor α but not tumor necrosis factor β in rheumatoid arthritis synovial fluid and serum

Saxne, T., Palladino, M. A., Heinegãrd, D., Talal, N., Wollheim, F. A.·1988·Arthritis & Rheumatism

Abstract

Synovial fluids from 6 of 12 patients with rheumatoid arthritis (RA) and from 3 of 11 patients with reactive arthritis contained measurable levels of tumor necrosis factor α (TNFα). Seven of 12 sera from RA patients contained TNFα, while only 1 of those from reactive arthritis patients was positive. Gamma‐inter‐feron was detected in the synovial fluids and sera of only the RA patients. Tumor necrosis factor β was not detected in any sera or synovial fluids. RA patients with detectable TNFα had higher erythrocyte sedimentation rates and synovial fluid leukocyte counts.

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.
