Preoperative sarcopenia negatively impacts short- and long-term outcomes of rectal cancer: A propensity score-matched analysis.
Article in Annals of gastroenterological surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Aim: Sarcopenia is associated with poor postoperative outcomes in various cancers; however, limited evidence is available for rectal cancer. Therefore, the present study examined the effects of skeletal muscle mass on the short- and long-term outcomes of rectal cancer. Materials and Methods: A total of 787 Stage I-IV rectal cancer patients who underwent curative resection between 2003 and 2021 at The University of Tokyo Hospital were included. We conducted a propensity score-matched analysis to mitigate confounding bias. The third lumber psoas muscle mass was measured to define sarcopenia. Results: Among 787 patients, 350 (44.5%) were classified as having sarcopenia. After matching, 532 patients were analyzed. Patient characteristics in the sarcopenia and nonsarcopenia groups were similar; however, the body mass index differed. The sarcopenia group had significantly higher rates of postoperative complications of all grades (33.1% vs 24.8%; Conclusion: Preoperative sarcopenia is associated with more total postoperative complications, more anastomotic leakage, and worse survival in rectal cancer patients.
