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

Toxic shock syndrome toxin 1 (TSST-1), a superantigen produced by Staphylococcus aureus, is a causative agent of toxic shock syndrome (TSS). This superantigen is a potent stimulator of T cells and macrophages/monocytes, resulting in the release of cytokines that are implicated in the pathogenesis of TSS. This study characterizes a mutant TSST-1, derived by site-directed mutagenesis, that has an alanine substitution at histidine 135 (mutant 135). This single-amino-acid change results in a mutant toxin that has lost mitogenic activity for T cells. In contrast to wild-type TSST-1, this mutant does not induce T cells to express interleukin-2, gamma interferon, or tumor necrosis factor beta (TNF-beta). The inability of mutant 135 to activate T cells is not due to a lack of binding to the class II major histocompatibility complex receptor. In addition, the mutant TSST-1 does not induce expression of TNF-alpha, which plays a role in the development of lethal shock. The lack of TNF-alpha induction by mutant 135 is likely due to its inability to activate T cells. These data suggest that the mutation at histidine 135 in TSST-1 affects toxin interactions with the T-cell receptor rather than the class II major histocompatibility complex receptor.
