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

backgroundThere is no consensus on the ideal surgical management of patients with Siewert type II gastroesophageal junctional (GEJ) cancers. Due to its anatomical location, total gastrectomy and oesophagectomy are widely used methods of resection. The aim of this study was to determine the optimal surgical treatment of these patients.

methodA systematic search of PubMed, Medline and Cochrane libraries was conducted for literature published between 2000 and 2022. Studies directly comparing oesophagectomy to gastrectomy for Siewert type II tumours were included. Outcome measures included rates of anastomotic leak, 30-day mortality, R0 resection and 5-year survival. Statistical analysis was performed using Review Manager 5.4.

resultsEleven studies involving 18,585 patients undergoing either oesophagectomy (n = 8618) or total gastrectomy (n = 9967) for Siewert type II GEJ cancer were included. There were no significant differences between the rates of anastomotic leak (OR 0.91, CI 0.59-1.40, p = 0.66) and R0 resection (OR 1.51, CI 0.93-2.42, p = 0.09). Patients undergoing total gastrectomy had a lower 30-day mortality (OR 0.66, CI 0.45-0.95, p = 0.03) and a greater 5-year overall survival (OR 1.49, CI 1.34-1.67, p < 0.001) compared to patients undergoing oesophagectomy. These differences were not statistically significant after excluding two large studies, which accounted for the majority of the total population in the analysis.

conclusionThese results suggest that total gastrectomy results in lower 30-day mortality and improved overall survival in patients with Siewert type II GEJ cancer. However, interpretation of these results may be biased by the effect of two large studies.
