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 diagnosis of sarcopenia emphasizes both, the quantity and quality of skeletal muscle. However, the impact of the combination of muscle quantity and quality on long-term survival remains unclear. This study aimed to assess the impact of the combination of skeletal muscle quantity and quality on long-term outcomes in patients with gastric cancer who underwent curative resection.

methodsWe retrospectively assessed 242 patients aged ≥ 65 ears who underwent curative gastrectomy between 2006 and 2015. The psoas muscle mass index (PMI) and intramuscular adipose tissue content (IMAC) were measured on preoperative computed tomography as skeletal muscle quantity and quality, respectively. The sarcopenia stage was classified by the combination of preoperative skeletal muscle quantity and quality (non-sarcopenia, sarcopenia, and severe sarcopenia). Prognostic factors for the 5-year overall survival (OS), non-cancer-specific survival (non-CSS), and cancer-specific survival (CSS) were evaluated by multivariable Cox regression.

resultsThe median follow-up period was 63.2 months. The non-sarcopenia, sarcopenia, and severe sarcopenia groups comprised 88, 121, and 33 patients (36.4%, 50.0%, and 13.6%), respectively. The severe sarcopenia group was older, and had a greater depth of invasion, than the non-sarcopenia group. Multivariable analysis revealed severe sarcopenia as an independent predictive indicator of OS (hazard ratio [HR] 4.01; 95% confidence interval [CI] 1.75 to 9.22) and non-CSS (HR 3.27; 95% CI 1.61 to 6.67), but not CSS.

conclusionsThe combination of preoperative skeletal muscle quantity and quality was useful for predicting survival, especially death from other diseases, in elderly patients who underwent gastrectomy for gastric cancer.
