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

backgroundSubmucosal tunneling endoscopic resection (STER) has been proved to be safe and effective for removal of esophageal leiomyoma originating from the muscularis propria (MP) layer. However, there are still technical challenges for tumors ≥35 mm due to the limited space of the submucosal tunnel. The aim of the study was to estimate the safety and efficacy of STER for large esophageal leiomyoma originating from the MP layer as well as compare its efficacy with video-assisted thoracoscopic surgery (VATS), which is a standard procedure for treating esophageal leiomyoma.

methodsWe retrospectively collected the clinical data of the patients with esophageal leiomyoma of 35-55 mm who underwent STER or VATS at our hospital between January 2010 and December 2014. Epidemiological data (gender, age), tumor location, tumor size, procedure-related parameters, complications, length of stay and cost were compared between STER and VATS.

resultsA total of 31 patients were enrolled, and 18 patients underwent STER and the other 13 received VATS. There was no significant difference between the two groups in gender, age, tumor location, tumor size, complications and rate of en bloc resection (P > 0.05). However, patients in the STER groups had a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost (P < 0.05). No recurrence was noted in the STER and VATS groups during a mean follow-up of 10.9 and 30.8 months, respectively.

conclusionsThe treatment efficacy was comparable between the STER and VATS for esophageal leiomyoma of 35-55 mm. However, STER is superior to VATS in a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost.
