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

objectiveSurgical indication in stage IIIA (N2) non-small cell lung cancer is still controversial. Hence, there is a need for the identification of predictors of the postoperative outcome in these patients. Although sarcopenia is expected to be a novel predictor of postoperative outcome in these patients, the underlying clinical features of sarcopenia have not been well investigated. Elevation of neutrophil/lymphocyte ratio indicates cancer-associated inflammation and depression of anticancer immunity. We analyzed the influence of sarcopenia on postoperative prognosis, and investigated the relationship between sarcopenia and neutrophil/lymphocyte ratio in patients with stage IIIA (N2) non-small cell lung cancer.

methodsWe retrospectively investigated 69 patients with stage IIIA (N2) non-small cell lung cancer. We used the L3 muscle index as a clinical measurement of sarcopenia, and divided patients into the sarcopenic (n = 21) and the non-sarcopenic group (n = 48). We then investigated the effect of sarcopenia on postoperative prognosis, and evaluated the correlation between sarcopenia and neutrophil/lymphocyte ratio.

resultsThis study included 47 males and 22 females. Univariate analysis revealed that sarcopenia, performance status, and serum cytokeratin-19 fragment level were predictors of poor prognosis; multivariate analysis revealed that performance status and sarcopenia were independent predictors of poor prognosis. The presence of sarcopenia was significantly correlated with neutrophil/lymphocyte ratio elevation.

conclusionsSarcopenia is a novel predictor of poor prognosis in patients with stage IIIA (N2) non-small cell lung cancer. Neutrophil/lymphocyte ratio elevation might be the reason for poor prognosis in sarcopenic patients.
