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

purposeThe aim of this systematic review and meta-analysis was to compare the oncological and perioperative outcomes of transhiatally extended gastrectomy (TEG) and thoracoabdominal esophagectomy (TAE) for therapy of adenocarcinomas of the esophagogastric junction (AEG) with focus on AEG type II, as the optimal approach for these tumors is still unclear.

methodsMEDLINE, EMBASE, and the Cochrane Library (CENTRAL) were searched until July 24, 2018. Studies comparing TAE and TEG for surgical treatment of AEG type tumors have been included. Patient's baseline and perioperative data have been extracted and meta-analyses have been conducted for the outcomes: number of dissected lymph nodes, R0-resection rate, anastomotic leak rate, postoperative morbidity, and 30-day mortality.

resultsOf 6709 articles identified, 8 studies have been included for further analysis. One thousand thirty-four patients underwent TAE, and 1177 patients TEG. No differences were found between the approaches in regard to number of dissected lymph nodes (MD - 0.96; 95% CI - 3.07 to 1.15; p = 0.37), R0-resection rates (OR 0.97; 95% CI 0.57 to 1.63; p = 0.90), anastomotic leak rates (OR 1.13; 95% CI 0.69 to 1.86; p = 0.63), and 30-day mortality (OR 1.53; 95% CI 0.90 to 2.61; p = 0.11). However, a higher rate of postoperative morbidity was found after TAE (OR 1.55; 95% CI 1.12 to 2.14; p = 0.008).

conclusionsThe optimal approach to surgical therapy of AEG II still remains unclear. This study identified a significantly higher rate of postoperative morbidity after TAE at comparable surgical outcomes. Due to major limitations concerning the quality of included studies, current data strongly mandates a properly designed randomized controlled trial to identify the optimal surgical approach for AEG type II tumors.
