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

backgroundAlthough a low skeletal muscle mass index (SMI) leads to poor overall survival (OS) after gastrectomy in patients with gastric cancer, the cutoff value that predicts long-term survival in patients with normal SMI remains unclear. This study aimed to determine the cutoff SMI value for predicting OS in patients with normal SMI.

methodsThis multicenter retrospective cohort study included patients with normal SMI who underwent radical gastrectomy for pStage I-III primary gastric cancer between January 2011 and December 2016. The patients were randomly divided at a 6:4 ratio into a training set, which examined the cutoff values for SMI, and a validation set, which validated the cutoff values. Patients were classified into high and low SMI groups according to the cutoff values. We compared OS between the high- and low-SMI groups using log-rank test and identified prognostic factors using Cox proportional hazards regression analysis.

resultsOf the 2516 patients, 1389 (55.2%) and 1127 (44.8%) were classified into the training and validation sets. We examined the cutoff values of SMI, which were 44.3 cm

conclusionsAmong patients with normal SMI, those with a lower SMI had poorer long-term survival after radical gastrectomy.
