Evaluation of sarcopenia and myosteatosis to determine the impact on mortality after emergency laparotomy.
Article in BJS open, 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
backgroundEmergency laparotomy is performed for a wide range of life-threatening conditions and is associated with significant morbidity and mortality. Risk prediction models facilitate accurate communication of operative risk with patients and relatives, in addition to benchmarking unit outcomes. Greater understanding of the impact of sarcopenia or myosteatosis will encourage the adoption of routine radiological reporting of body composition and the incorporation of skeletal muscle gauge (SMG) into risk prediction models. This study investigated the prognostic significance of SMG, an aggregate assessment of sarcopenia or myosteatosis, in patients who had undergone an emergency non-trauma-related laparotomy.
methodsThis was a retrospective cohort study of patients aged ≥ 18 years who underwent an emergency laparotomy at the Queen Elizabeth Hospital between January 2014 and December 2020. Body composition and patient outcomes were analysed.
resultsIn all, 1090 patients with a mean(standard deviation) age of 62.3(17.5) years underwent emergency laparotomy (bowel obstruction, 52.7%; perforation, 26.3%; ischaemia, 9.5%). Overall 30- and 90-day mortality was 10.0% and 11.6%, respectively. On multivariate analysis, low SMG was associated with worse 30- and 90-day mortality, with odds ratios of 2.12 (95% confidence interval (c.i.) 1.18 to 3.83; P = 0.012) and 2.64 (95% c.i. 1.55 to 4.48; P < 0.001), respectively. Low SMG was also associated with an increased length of hospital stay (odds ratio 1.45; 95% c.i. 1.22 to 1.72; P < 0.001).
conclusionA low SMG was associated with increased postoperative mortality and length of hospital stay after emergency laparotomy. Patients undergoing computed tomography imaging for acute abdominal pain should undergo routine reporting of body composition.
