Impact of Sarcopenia and Its Severity on Postoperative Functional Decline in Patients Undergoing Cardiac Surgery.
Article in JMA journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: In this study, we aimed to evaluate the impact of sarcopenia and its severity on postoperative functional decline in patients undergoing cardiac surgery. Methods: This retrospective cohort study included 161 patients (median age, 71 years; 75.8% male) who underwent elective cardiac surgery at a tertiary care hospital between April 2021 and November 2024. Functional decline was assessed by subtracting the preoperative Barthel Index (BI) score from the score at discharge. Sarcopenia severity was assessed based on the Asian Working Group for Sarcopenia 2019 criteria. Multiple linear regression models adjusted for relevant clinical and demographic factors were used to examine the associations among sarcopenia, severe sarcopenia, and functional decline. Results: The mean (standard deviation) change in BI score was -1.4 (5.7). The overall prevalence of sarcopenia was 21.1%, comprising 7.5% (non-severe) sarcopenia and 13.7% severe sarcopenia cases. In the multivariate analysis, the presence of sarcopenia was significantly associated with postoperative functional decline (β = -0.185, p = 0.001), whereas severe sarcopenia exhibited a stronger association with postoperative functional decline (β = -0.268, p < 0.001). Conclusions: These findings indicate that patients with severe sarcopenia require careful attention because of their higher risk of postoperative functional decline.
