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
Fibroblast growth factor 21 (FGF21) is a key regulator of metabolism and cardiovascular health. However, its upregulation in aging and age-related disorders suggests the presence of FGF21 resistance. This study aimed to elucidate the mechanisms underlying senescence-associated FGF21 resistance in human umbilical vein endothelial cells (HUVECs) and to explore potential therapeutic interventions. Transcriptomic analysis revealed a significant reduction in the number of FGF21-regulated genes in senescent HUVECs compared to young cells, indicating the onset of FGF21 resistance. In young HUVECs, FGF21 inhibited inflammatory cytokines and upregulated mitochondrial ribosomal protein genes. Conversely, senescent HUVECs showed a downregulation of β-klotho, an essential co-receptor for FGF21, at the cell membrane, concomitant with an upregulation of ADAM10, a protease involved in β-klotho degradation. These changes were also observed in aged mouse aortas. ADAM10 was shown to bind directly to β-klotho and promote its degradation, contributing to FGF21 resistance. Inhibition of ADAM10 or overexpression of β-klotho restored FGF21 responsiveness in senescent HUVECs. Moreover, pharmacologically high concentrations of FGF21 were effective in overcoming resistance and restoring its regulatory effects on senescent cells. These findings suggest that ADAM10-mediated degradation of β-klotho is a central mechanism in the development of FGF21 resistance, and that targeting the ADAM10/β-klotho axis could represent a novel therapeutic approach to restore FGF21 sensitivity. Pharmacological administration of FGF21 may hold promise in treating vascular aging and its associated cardiovascular pathologies.
