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

purposeWe performed a combined assessment of skeletal muscle mass using the skeletal muscle mass index (SMI) and the psoas muscle index (PMI) to evaluate their association with the overall survival (OS) of gastric cancer patients after curative gastrectomy.

methodsWe analyzed, retrospectively, the computed tomography records of skeletal muscle mass of patients who underwent radical gastrectomy for pStage I-III gastric cancer between April, 2010 and April, 2016. We then compared OS as the primary outcome, stratifying patients according to their SMI or PMI, and investigated prognostic factors using multivariate analyses.

resultsThe median follow-up duration was 62 months. Of the 550 patients analyzed, 262 (47.6%), 194 (35.3%), and 94 (17.1%) were classified into normal, single-low, and double-low SMI and PMI groups, respectively. Patients with double-low SMI and PMI had the poorest OS (P = 0.018). Multivariate analysis revealed that double-low indices were an independent prognostic factor for poor OS (hazard ratio, 1.808; 95% confidence interval 1.009-3.238; P = 0.046).

conclusionsThis study revealed that evaluation of skeletal muscle mass based on the combined SMI and PMI can predict the survival outcomes of patients after curative gastrectomy for gastric cancer, and that the coexistence of a low-SMI and low-PMI was associated with the poorest survival.
