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

Acute appendicitis is one of the most common causes of abdominal pain in children but remains a diagnostic challenge, and insight into the aetiology of the condition is lacking. A case of simultaneous acute appendicitis in monozygotic twin boys is reported here. Familial aggregation in acute appendicitis has been described, but the underlying causes for this are not well understood. The patients reported here were both genetically identical and lived a mostly identical lifestyle. Their simultaneous presentation would be exceedingly rare if explained entirely by chance, suggesting a role for both genetic and environmental influences. Increased knowledge of this occurrence may assist in prompt diagnosis and reporting on the incidence and timing of appendicitis in monozygotic twins could better elucidate the genetic and environmental factors that predispose to this disease.
