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

BACKGROUND AND

aimA number of recent studies have been published evaluating the chemopreventive effect of aspirin against gastric cancer, and an updated meta-analysis is required to evaluate this relationship further. This study presents a meta-analysis of studies examining the effect of aspirin on gastric cancer incidence and death.

methodsThe PUBMED and Cochrane Central Registration of Controlled Trials databases were searched for eligible studies published up to December 2018. Pooled risk ratios for gastric cancer incidence and death in aspirin users

resultsThe meta-analysis comprised 33 studies with a total of 1 927 971 patients. The pooled risk ratios for gastric cancer incidence in the fixed- and random-effects models were 0.890 (95% confidence interval, 0.871-0.909) and 0.826 (0.740-0.922), respectively. In Asia and North America, the maximum preventive benefit of aspirin use was observed with weekly or daily use. Aspirin use was most effective for noncardiac gastric cancer. The pooled risk ratios for gastric cancer death in the fixed- and random-effects models were 0.798 (0.749-0.850) and 0.894 (0.780-1.024), respectively. Significant heterogeneity was observed among studies of gastric cancer incidence but not gastric cancer death.

conclusionAspirin use may reduce the risk of gastric cancer incidence and death; however, the relationship may be limited to a specific frequency and duration of aspirin use and geographic location.
