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

backgroundOesophageal diverticula are rare outpouchings of the oesophagus which may be classified anatomically as pharyngeal (Zenker's), mid-oesophageal and epiphrenic. While surgery is indicated for symptomatic patients, no consensus exists regarding the optimum technique for non-Zenker's oesophageal diverticula. The aim of this study was to determine the outcome of surgery in patients with non-Zenker's oesophageal diverticula.

methodsPubMed, MEDLINE and the Cochrane Library (January 1990 to January 2016) were searched for studies which reported outcomes of surgery in patients with non-Zenker's oesophageal diverticula. Primary outcome measure was the rate of staple line leakage.

resultsTwenty-five observational studies involving 511 patients (259 male, median age 62 years) with mid-oesophageal (n = 53) and epiphrenic oesophageal (n = 458) diverticula who had undergone surgery [thoracotomy (n = 252), laparoscopy (n = 204), thoracoscopy (n = 42), laparotomy (n = 5), combined laparoscopy and thoracoscopy (n = 8)] were analysed. Myotomy was performed in 437 patients (85.5%), and anti-reflux procedures were performed in 342 patients (69.5%). Overall pooled staple line leak rates were reported in 13.3% [95% c.i. (11.0-15.7), p < 0.001] and were less common after myotomy (12.4%) compared with no myotomy (26.1%, p = 0.002).

conclusionsNo consensus exists regarding the surgical treatment of non-Zenker's oesophageal diverticula, but staple line leakage is common and is reduced significantly by myotomy.
