Rapid clearance of the lupus antigen Sm is delayed by autoantibody: a possible mechanism of autoimmunity perpetuation.
Article in Clinical and experimental immunology, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sm ribonucleoprotein complex was immunopurified and labelled with 125I. After i.v. injection into normal mice 125I-Sm was cleared with a half life of less than 3 min, mainly to the liver (54% at 15 min). With time there was a progressive reduction in liver uptake (13.3% at 1 h), and this was associated with the appearance of increasing amounts of trichloroacetic acid soluble 125I in serum, suggesting complete Sm catabolism. Injection of 125I-Sm as a preformed immune complex with human anti-Sm antibody was associated with slower antigen removal from the circulation (half life 15 min), more gradual liver uptake (27% at 1 hr), and less degradation products in the serum than after injection of antigen alone. These data suggest that release of 125I-Sm into the circulation is followed by specific organ uptake and antigen degradation. In the form of an immune complex, the rapid removal mechanism is impaired, and antigen persists in the circulation in an undegraded form. Simultaneous production of anti-Sm antibody and Sm antigen release following tissue destruction could lead to amplification of any primed immune response as a result of autoantigen drive in systemic lupus erythematosus.
