Effect of progressive sarcopenia during postoperative 6 months on long-term prognosis of completely resected lung cancer.
Article in Journal of thoracic disease, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundPreoperative sarcopenia has been indicated to be a potential prognostic factor for patients after complete resection of lung cancer. This study evaluated whether changes in the skeletal muscle mass index (SMI) over postoperative 6 months could predict long-term prognosis from 6 months after complete resection of non-small cell lung cancer (NSCLC).
methodsThis retrospective study analyzed data of 468 patients who underwent curative lobar resection for non-small cell lung cancer at our hospital. The 6-month postoperative change in SMI was calculated, and associations between clinicopathological factors (including the change in SMI) and postoperative mortality were examined.
resultsRates of overall survival were 90.6% after 3 years and 80.7% after 5 years. The median 6-month change in SMI was -3.4% (range, -22.3% to 14.7%). Multivariate analysis revealed that poor outcomes were independently predicted by a large change in SMI, age, pathological stage, lymphovascular invasion, and a Brinkman index of ≥600. Through the analysis in training and validation sets, we determined a cut-off value of -9.9% for the 6-month postoperative change in SMI. Subgroup analysis showed that depletion of SMI during postoperative 6 months was a risk factor for poorer prognosis only in heavy smokers with a Brinkman index of ≥600.
conclusionsA reduction in SMI during the 6 months after complete resection of non-small cell lung cancer significantly predicted prognosis, especially in heavy smokers. These results suggest that attention should be given to prevent the perioperative progression of sarcopenia after curative resection of lung cancer. Thoracic surgeons should take how to manage perioperatively against sarcopenia into consideration.
