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

backgroundSince 1910, omentectomy has been an essential component of radical gastrectomy for advanced gastric cancer. However, researchers have recently questioned the benefit of omentectomy in radical gastrectomy. The aim of this meta-analysis was to compare omentectomy and omentum preservation in gastrectomy for advanced gastric cancer in terms of survival outcomes and short-term outcomes.

methodsThe PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched. Studies that compared omentum preservation with omentectomy were included. Overall survival (OS) and relapse-free survival (RFS) were analyzed as primary outcomes.

resultsOf 3509 records screened, one randomized clinical trial and five propensity-score matched retrospective studies with 1661 patients were selected. Omentum preservation was associated with improved OS (hazard ratio [HR] = 0.757, 95% confidence interval [CI] = 0.603-0.950, P = 0.016, I

conclusionsBasing on the current literature, gastrectomy with omentum preservation was associated with improved OS and short-term outcomes compared with omentectomy for advanced gastric cancer. Further randomized trials are required to confirm the survival benefit of omentum-preserving gastrectomy.
