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

aimIn clinical practice, endoscopic resection of submucosal tumors (SMTs) in the gastric fundus is extremely difficult. The aim of our study was to compare the efficiency and safety of the double-bending method (DBM) and conventional endoscopic submucosal dissection (ESD) for the treatment of SMTs in the gastric fundus.

methodsThe clinical data of 190 patients who underwent resection of SMTs in the gastric fundus were retrospectively analyzed.

resultsIn all, 190 patients with an average age of 53 years were included in this study: 100 patients in the DBM-ESD group and 90 patients in the ESD group. The average operation time was 54.2 min in the DBM-ESD group and 101.6 min in the ESD group (P < 0.001), which indicates that the resection speed was significantly faster in the DBM-ESD group. Subgroup analysis revealed that the larger the tumor volume was, the greater the difference in operation time between the two groups. No significant difference was observed in intraoperative or postoperative complications.

conclusionsDBM-ESD can be safely and effectively performed to resect SMTs in the gastric fundus and is especially suitable for patients with very large tumor diameters.
