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

backgroundSerum tryptase levels reflect mast cell activation and correlate with anaphylactic reactions. Elevated post-mortem serum tryptase levels have been found in witnessed fatal anaphylaxis.

objectiveThis study was designed to examine whether or not unwitnessed anaphylaxis may be a hitherto unrecognized cause of sudden unexplained death.

methodsMast cell tryptase was measured by immunoassay in 68 post-mortem sera remaining from a previous study which reported elevated venom-specific IgE antibodies in 22 (23%) of 94 victims of sudden unexpected death. Autopsies were performed in all cases. The cause of death was independently reported by pathologists unfamiliar with the nature of this study.

resultsSerum tryptase levels were elevated (> 10 ng/mL) in nine of 68 cases. The levels could not be predicted from the clinical circumstances surrounding death. Sera from four individuals contained both elevated tryptase and previously reported elevated venom-specific IgE.

conclusionsWe conclude that mast cell activation may accompany up to 13% of sudden unexpected deaths in adults. Measurement of both tryptase and specific IgE antibody levels in post-mortem sera from persons experiencing sudden, unexpected death may identify a small subset of cases due to clinically unrecognized fatal anaphylaxis, including those due to insect stings.
