FGF21 and its underlying adipose tissue-liver axis inform cardiometabolic burden and improvement in obesity after metabolic surgery.
Article in EBioMedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThis research investigates the determinants of circulating FGF21 levels in a cohort reflecting metabolic disease progression, examining the associations of circulating FGF21 with morphology and function of adipose tissue (AT), and with metabolic adjustments following metabolic surgery.
methodsWe measured serum FGF21 in 678 individuals cross-sectionally and in 189 undergoing metabolic surgery longitudinally. Relationships between FGF21 levels, AT histology, transcriptomes and proteomes, cardiometabolic risk factors, and post-surgery metabolic adjustments were assessed using univariate and multivariate analyses, causal mediation analysis, and network integration of AT transcriptomes and proteomes.
findingsFGF21 levels were linked to central adiposity, subclinical inflammation, insulin resistance, and cardiometabolic risk, and were driven by circulating leptin and liver enzymes. Higher FGF21 were linked with AT dysfunction reflected in fibro-inflammatory and lipid dysmetabolism pathways. Specifically, visceral AT inflammation was tied to both FGF21 elevation and liver dysfunction. Post-surgery, FGF21 peaked transitorily at three months. Mediation analysis highlighted an underlying increased AT catabolic state with elevated free fatty acids (FFA), contributing to higher liver stress and FGF21 levels (total effect of free fatty acids on FGF21 levels: 0.38, p < 0.01; proportion mediation via liver 32%, p < 0.01). In line with this, histological AT fibrosis linked with less pronounced FGF21 responses and reduced fat loss post-surgery (FFA and visceral AT fibrosis: rho = -0.31, p = 0.030; FFA and fat-mass loss: rho = 0.17, p = 0.020).
interpretationFGF21 reflects the liver's disproportionate metabolic stress response in both central adiposity and after metabolic surgery, with its dynamics reflecting an AT-liver crosstalk.
