1 · What the graph read from it

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.

2 · The registry

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

Pelargonidin, a natural anthocyanidin, is known for its anti-inflammatory, antioxidant, and cytoprotective properties, however its role in myocardial fibrosis remains unclear. This study explored the therapeutic potential of pelargonidin in a mouse model of isoproterenol (ISO)-induced myocardial fibrosis. Male C57BL/6 mice were treated with ISO and subsequently administered either a low (20 mg/kg/day) or high (40 mg/kg/day) dose of pelargonidin, with captopril (15 mg/kg/day) serving as a reference control. Histological analysis revealed that pelargonidin significantly reduced collagen deposition in the myocardium in a dose-dependent manner. Molecular assessments showed decreased protein expression of alpha-SMA, COL3A1, and FN1, along with downregulation of TGF-beta/Smad2/3 signaling, as evidenced by reduced levels of TGF-beta and phosphorylated Smad2/3. Additionally, pelargonidin suppressed the expression of extracellular matrix-related genes and decreased circulating levels of Th2 cytokines IL-4 and IL-13. These findings indicate that pelargonidin mitigates myocardial fibrosis by targeting the TGF-beta/Smad2/3 pathway and modulating Th2-mediated immune responses. Overall, the results suggest that pelargonidin may serve as a promising therapeutic agent for myocardial fibrosis and related cardiovascular disorders.
