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

backgroundObesity, gastroesophageal reflux, and Barrett's esophagus have all been linked to esophageal adenocarcinoma. In addition, the decline in Helicobacter pylori (H. pylori) infection in affluent societies has also been suggested to be a major factor in the recent rise in the incidence of esophageal adenocarcinoma. If H. pylori infection has a protective role, populations with a naturally low prevalence of H. pylori infection such as the ethnic Malays of Northeastern Peninsular Malaysia should have high rates of esophageal adenocarcinoma.

aimTo test this hypothesis, we investigated the incidence of esophageal carcinoma among the ethnic Malays of the state of Kelantan in Northeastern Peninsular Malaysia.

methodsThe pathology services in the state of Kelantan are provided by two main hospitals. The histopathological records of both hospitals were systematically examined to retrieve all cases of esophageal carcinoma diagnosed between 2004 and 2008. Incidence rates were determined based on the most recent population census.

resultsThe age-standardized incidence rates (per 100,000 population) of esophageal adenocarcinoma among Malay men and women were 0.75 and 0.69, respectively. The corresponding rates for squamous cell carcinoma of the esophagus were 0.66 and 1.34, respectively.

conclusionsThe low rates of adenocarcinoma and squamous cell carcinoma of the esophagus in the study area, despite the fact that H. pylori infection is virtually absent, does not support the hypothesis that the absence of H. pylori infection is a pivotal factor in the pathogenesis of these cancers.
