Impact of preoperative frailty and sarcopenia on short-term functional recovery after cardiac surgery in elderly patients: a prospective cohort study.

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 and frailty are associated with poor outcomes in elderly patients undergoing cardiac surgery; this study aimed to investigate the effects of sarcopenia and frailty on postoperative recovery in elderly patients.
methodsThis prospective cohort study included 566 patients aged ≥60 years with an American Society of Anaesthesiologists (ASA) II-IV status who were scheduled for elective open-heart surgery between June 30, 2024, and April 5, 2026. Frailty was assessed using the Comprehensive Geriatric Assessment Frailty Index (CGA-FI). Sarcopenia was diagnosed based on the CT-based skeletal muscle index (SMI), grip strength, and physical function. The primary outcome was worsening disability or death within 3 months after surgery.A multivariate logistic regression model was used to estimate the association of sarcopenia and/or frailty with worsening disability or death within 3 months after surgery.
resultsPatients with sarcopenia and frailty did not experience a reduction in disability burden within 3 months postoperatively [-2.0 (IQR: -9.0, 21.2)]. In contrast, patients with sarcopenia only and those with frailty only had significant reductions in the overall disability burden [-5.0 (IQR: -7.0, 0.0) and -5.0 (IQR: -8.0, -1.0)]. Compared with normal patients, those with both sarcopenia and frailty (OR = 3.09; 95% CI 1.61-5.96), those with sarcopenia only (OR = 2.65; 95% CI 1.38-5.12), and those with frailty only (OR 1.93; 95% CI 1.01-3.72) had a significantly increased risk of worsening disability or death within 3 months post-surgery.
conclusionFrailty, sarcopenia, and their combination are associated with a significantly increased risk of worsening disability or death within 3 months after surgery. Notably, compared with patients with both sarcopenia and frailty, those with frailty alone or sarcopenia alone have a lower burden of postoperative disability.
