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

Severe acute respiratory syndrome-associated coronavirus (SARS-CoV) infection causes lung failure characterized by atypical pneumonia. We previously showed that antibodies against SARS-CoV spike domain 2 (S2) in the patient sera can cross-react with human lung epithelial cells; however, the autoantigen is not yet identified. In this study, we performed proteomic studies and identified several candidate autoantigens recognized by SARS patient sera in human lung type II epithelial cell A549. Among the candidate proteins, annexin A2, which was identified by mass spectrometry analysis and had the highest score by Mascot data search, was further characterized and investigated for its role as an autoantigen. By confocal microscopic observation, SARS patient sera and anti-S2 antibodies were co-localized on A549 cells and both of them were co-localized with anti-annexin A2 antibodies. Anti-annexin A2 antibodies bound to purified S2 proteins, and anti-S2 bound to immunoprecipitated annexin A2 from A549 cell lysate in a dose-dependent manner. Furthermore, an increased surface expression and raft-structure distribution of annexin A2 was present in A549 cells after stimulation with SARS-induced cytokines interleukin-6 and interferon-gamma. Cytokine stimulation increased the binding capability of anti-S2 antibodies to human lung epithelial cells. Together, the upregulated expression of annexin A2 by SARS-associated cytokines and the cross-reactivity of anti-SARS-CoV S2 antibodies to annexin A2 may have implications in SARS disease pathogenesis.
