1 · What the graph read from it

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.

2 · The registry

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

Histone H2B is a common target of autoantibodies in both spontaneous and drug-induced systemic lupus erythematosus (SLE). Recent studies demonstrate that Asp(25) of histone H2B (H2B) spontaneously converts to an isoaspartic acid (isoAsp) in vivo. Our laboratory has demonstrated that the posttranslational modification of an aspartic acid to an isoaspartic acid within self-peptides renders otherwise ignored peptides immunogenic. Analysis of serum from lupus-prone mice and histone antibody positive SLE patients revealed antibodies specific to the Asp and isoAsp H2B(21-35) peptide, and that the expression of these antibodies is dependent on TLR9. IsoAsp H2B(21-35) is immunogenic in non-autoimmune prone mice and mice lacking the ability to repair isoAsp have significantly reduced levels of antibodies to H2B. Asp H2B(21-35) incubated at physiological temperatures and pH acquires the isoAsp modification, demonstrating that H2B(21-35) is prone to spontaneous isoAsp formation in vivo. Autoimmunity to isoAsp H2B suggests that this form of the autoantigen may be critical in the induction of anti-histone autoantibodies in human SLE and in murine models of disease.
