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

backgroundLung cancer patients frequently suffer from sarcopenia, and reports on the association of resectable lung cancer and their postoperative outcomes are increasing. Information on whether sarcopenia has any impact on short- and long-term postoperative outcomes in patients surgically treated for non-small cell lung cancer remains insufficient. Furthermore, reports vary regarding the pathological stage, surgical procedure, diagnostic tool of sarcopenia, cut-off value, prognosis, and postoperative complications. We believe that sarcopenia assessment should be included as one of the factors which affect the surgical outcomes of lung cancer. Thus, we conducted a review and meta-analysis to ascertain the association between sarcopenia and postoperative outcomes.

methodsWe performed a systematic literature search in PubMed/MEDLINE. Studies included cases defined sarcopenia, received lung cancer surgery, assessed postoperative complications, and prognosis. The pooled odds ratios for survival and postoperative complications, with 95% confidence intervals, were generated using Review manager 5.3.

resultsA total of ten retrospective studies were eligible for this meta-analysis, including a total of 2,643 non-small cell lung cancer patients. All reviews used skeletal muscle mass as a diagnostic tool for sarcopenia. Sarcopenia was associated with worse survival outcomes and increased postoperative complications in patients with resected lung cancer.

conclusionsSarcopenia is an independent risk factor for postoperative death and postoperative complications in patients who have undergone surgery. It is necessary to explore the mechanism of sarcopenia and optimal intervention, such as exercise, nutrition, or drug therapy.
