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

backgroundThe incidence of adenocarcinoma of the esophagogastric junction (AEG) has rapidly increased in recent years. Popular surgical approaches for AEG are proximal gastrectomy (PG) and total gastrectomy (TG), but it is controversial as to which approach is superior. Therefore, we conducted a systematic review and meta-analysis to evaluate the short- and long-term clinical outcomes of PG and TG for AEG.

methodsPubMed, Embase, Web of Science, and Cochrane Library were searched from inception to 1 June 2021. The Newcastle-Ottawa scale was used to conduct quality assessments, and RevMan (Version 5.4) was used to perform the meta-analysis.

resultsIn all, 1,734 patients with Siewert II/III AEG in 12 studies were included in the meta-analysis. PG was associated with less number of harvested lymph nodes (WMD =  - 9.00, 95% CI - 12.61 to - 5.39, P < 0.00001), smaller tumor size (WMD =  - 1.02, 95% CI - 1.71 to - 0.33, P = 0.004), shorter hospital length of stay (WMD =  - 3.99, 95% CI - 7.27 to - 0.71, P = 0.02), and better long-term nutritional status compared with TG. Overall complications, other complications, and overall survival were not significantly different between the two groups. Moreover, subgroup analysis revealed that the occurrence of anastomotic strictures and reflux esophagitis was associated with the use of novel gastrointestinal tract (GI) anastomoses (double-tract reconstruction, jejunal interposition, and semi-embedded valve anastomosis) after PG.

conclusionsBased on the available evidence, we recommend that surgeons accept PG combined with multiple novel anastomoses as an optimal surgical approach in patients diagnosed with resectable Siewert type II/III AEG.
