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

backgroundThe endoscopic resection of gastrointestinal mesenchymal tumors (GIMTs) is widely accepted because of its minimal invasiveness. However, one major concern is the high rate of positive microscopic margins remaining following endoscopic resection, which was thought to be related to a higher risk of recurrence. This study aimed to determine whether positive margins affect the recurrence rate of gastric GIMTs and the factors associated with positive margins.

methodsPatients with gastric GIMTs were recruited retrospectively from January 2008 to December 2013. Clinical and pathological features, endoscopic procedure information, and follow-up data were collected and analyzed.

resultsThe study included 777 patients. All tumors were removed along with the pseudocapsule without macroscopic residual (ER0), and the median tumor size was 15.2 mm (range 3-100 mm). Pathological evaluation revealed 371(47.7%) GISTs. The rate of microscopic R1 resection rate was 47.0% (443/777). In a stepwise multivariate analysis, a significantly increased incidence of R1 resection was recorded for the GISTs (OR 11.13, 95% CI 3.00-41.37). In a subgroup analysis of GISTs, a univariate analysis revealed that EFTR achieved a higher rate of R0 resection (OR 0.56, 95% CI 0.31-1.00), but it was proven insignificant in a stepwise multivariate analysis. Local recurrence occurred in two patients (0.3%) during a mean follow-up time of 34.2 months. Differences in the recurrence rates between the R0 and R1 groups were statistically insignificant (P = 0.841).

conclusionsR1 resection for gastric GIMTs is not related to a higher recurrence rate than R0 resection, and ER0 resection is sufficient for gastric GIMTs.
