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

backgroundGastric cancer (GC) is one of the most common worldwide cancers and causes of death. Various studies have investigated the effect of metformin on overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and recurrence rate in diabetic patients after gastrectomy, and their results have been contradictory. This meta-analysis aimed to evaluate the effect of metformin use compared to sulfonylurea compounds with OS, CSS, RFS, and recurrence rate after gastrectomy in diabetic patients.

methodsWe reviewed the Scopus, Google Scholar, PubMed, Web of Science, and Embassy databases until September 2022 based on appropriate MESH terms. All observational studies that evaluated the effect of metformin on survival in diabetic patients who underwent surgery for GC were included. The hazard ratio (HR) with a 95% confidence interval was used to estimate the effect size. The Egger test was used to evaluate publication bias.

resultsOverall, nine studies, including 245,387 GC patients who underwent surgery, were included. The use of metformin significantly increased the OS rate (HR: 0.81, 95% CI: 0.78, 0.86, P: 0.001, I

conclusionThe use of metformin in diabetic patients with GC can be associated with improved OS, CSS, RFS, and reduced recurrence rate after gastrectomy, especially in the Asian population.
