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
This study evaluated the cardioprotective effects of Alpinia galanga rhizome extract (GRE) against noise-induced myocardial injury via phytochemical profiling, molecular docking, and in vivo assessment. Male Wistar rats (n = 6/group) were assigned to the following four groups: control (C), control + GRE (100 mg/kg), noise-exposed (N), and noise-exposed + GRE (N+GRE, 100 mg/kg). Rats in the N and N+GRE groups were exposed to 90 dB(A) white noise for 2 h/day for 28 days, with GRE administered orally throughout the exposure period. Phytochemical analysis confirmed the presence of flavonoids and phenolic acids with known antioxidant and anti-inflammatory activities. In vitro, GRE significantly reduced nitric oxide production in lipopolysaccharide-stimulated RAW264.7 macrophages. In vivo, noise exposure elevated cardiac malondialdehyde levels, impaired antioxidant enzyme activity, and increased circulating tumor necrosis factor-alpha (TNF-α) and heme oxygenase-1 (HO-1) levels. GRE treatment restored redox balance, suppressed proinflammatory mediator levels, and improved histopathological alterations. Molecular docking analysis indicated strong binding of GRE phytoconstituents to HO-1 and TNF-α, supporting the observed in vivo effects. These findings demonstrate that GRE mitigates noise-induced cardiac injury through its antioxidant and anti-inflammatory properties, highlighting its therapeutic potential.
