Opportunistic computed tomography-based sarcopenia screening and mortality after liver transplantation: a systematic review and meta-analysis.

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
objectiveThe aim of this study was to investigate the diagnosis of sarcopenia in chronic liver disease by opportunistic computed tomography screening using the Psoas Muscle Index method as a predictor of mortality after liver transplantation.
methodsWe systematically searched PubMed, Scopus, and Cochrane Central Register of Controlled Trials from July 2014 to July 2024. We restricted inclusion in this meta-analysis to observational studies and clinical trials on adult patients with chronic liver disease diagnosed with sarcopenia by computed tomography undergoing liver transplantation or on a waiting list. We included the one with a larger sample size for studies with overlapping populations. We excluded studies with therapeutic interventions, animal experiments, cell-line studies, editorial pieces, commentaries, review articles, and case reports.
resultsAfter the removal of duplicate records and ineligible studies, 163 remained and were thoroughly reviewed based on inclusion criteria. Of these, a total of 11 studies were included in qualitative synthesis and four studies were included in quantitative analysis (meta-analysis), comprising 382 patients. Patients with muscle mass loss after liver transplantation diagnosed by computed tomography scan using the Psoas Muscle Index method had a 4.1 times higher risk of death than non-sarcopenic patients (random-effects model: OR 4.1386; 95%CI 2.4215-7.0730; p<0.0001). Interpretatively, a scale with an I2 value close to 0% indicates no heterogeneity. The other criteria also did not reject the hypothesis of homogeneity among the articles.
conclusionsPatients with muscle mass loss diagnosed by computed tomography using the Psoas Muscle Index method had a fourfold increased mortality risk after transplantation. The findings reinforce the need to identify sarcopenic patients preoperatively to optimize liver transplantation outcomes. Using the Psoas Muscle Index, an opportunistic diagnosis by computed tomography scan can be helpful in this setting.
