Risk factors for progressive sarcopenia 6 months after complete resection of lung cancer: what can thoracic surgeons do against sarcopenia?
Article in Journal of thoracic disease, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundOur previous report described how postoperative progression of sarcopenia predicted long-term prognosis after complete resection of non-small cell lung cancer (NSCLC) in heavy smokers. However, there are currently no effective means to treat progressive sarcopenia. In this study, we aimed to confirm our previous findings in a larger population and to identify factors associated with postoperative progression of sarcopenia to propose possible preventative measures.
methodsThis retrospective study analyzed the data of 1,095 patients who underwent curative lobar resection for NSCLC at Kanagawa Cancer Center. We divided patients into four groups according to sex and Brinkman index (BI) above or below 600. Six-month postoperative changes in the skeletal muscle index (SMI) were calculated and associations between clinicopathological factors including changes in SMI and mortality from postoperative 6 months were examined. Only in groups in which postoperative depletion of SMI was shown to be associated with the prognosis, we identified clinicopathological factors associated with depletive SMI.
resultsThe overall survival rates of 1,095 patients were 89.8% and 82.5% at 3 and 5 years, respectively. The median 6-month change in SMI was -3.4% (range, -22.3% to +17.9%). Multivariate analysis revealed that poor prognosis was independently predicted by a large reduction in the SMI (cut-off value: -10%) in males with a BI ≥600. In 391 heavy-smoking males, factors associated with a postoperative change in SMI ≤-10% were history of other cancers (including gastric cancer) low forced expiratory volume in one second (FEV 1.0, cut-off value: 1,870 mL), and prolonged operation time (cut-off value: 200 minutes).
conclusionsPerioperative measures to prevent postoperative sarcopenia are appropriate for heavy smokers. We obtained some clues regarding countermeasures, one of which may be avoiding long-time operation. Further studies including clinical trials to assess perioperative anti-sarcopenia treatments, are needed.
