Effect of reduction in skeletal muscle quantity and sex differences on postoperative hepatic steatosis following total pancreatectomy.
Article in Surgery today, 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
purposeThis study aimed to determine the risk factors for new-onset hepatic steatosis after total pancreatectomy (TP), focusing on muscle loss and sex.
methodsWe retrospectively analyzed 100 patients who underwent TP between 2005 and 2024. Nutritional parameters, BMI, muscle volume, and liver status were evaluated. Logistic regression and subgroup analyses were performed to identify the risk factors for hepatic steatosis.
resultsThe prevalence of hepatic steatosis increased from 3.0% preoperatively to 24.0% at 3-6 months after TP. Female patients showed a significantly higher incidence of hepatic steatosis than male patients (37.8% vs. 12.7%, respectively). A multivariate analysis identified female sex (odds ratio: 7.77, 95% confidence interval: 2.03-29.8, p = 0.009), younger age (0.93, 0.88-0.98, 0.011), and higher preoperative BMI (1.28, 1.05-1.63, 0.015) as independent risk factors. Among the female patients, a younger age, one-stage TP, greater reductions in SMI, portal vein resection, longer operative time, greater blood loss, and diarrhea at discharge were associated with new-onset hepatic steatosis. However, a lower intraoperative blood loss potentially contributes to recovery from hepatic steatosis after TP.
conclusionsA female sex is a high risk factor for hepatic steatosis after TP. Reducing operative stress and preserving muscle volume may facilitate the prevention and recovery from hepatic steatosis.
