Modulatory effects of 6-Gingerol on erythrocyte deformability and morphology following lower extremity skeletal muscle ischemia-reperfusion injury in rats.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Oxidative stress from ischemia-reperfusion (IR) injury severely compromises erythrocyte deformability, a critical factor that disrupts microvascular flow and thereby exacerbates reperfusion injury. This study provides a novel perspective by directly investigating the protective effects of 6-Gingerol, known for its potent antioxidant properties, on erythrocyte function in a rat model of lower-extremity skeletal muscle IR. Twenty-four Wistar albino rats were divided into four groups: Sham (n = 6), DMSO (n = 6), IR (n = 6), and 6-Gingerol-IR (6G-IR, n = 6, 6 mg/kg i.p., 1 h before ischemia). Ninety minutes of ischemia were followed by 90 min of reperfusion. Compared to the IR group, the 6G-IR group exhibited a significant improvement in erythrocyte deformability (Rrel 2.13 ± 0.36 vs. 3.29 ± 0.40; p = 0.002, Cohen’s d = 3.9), a substantial reduction in lipid peroxidation (MDA 16.23 ± 2.11 vs. 22.14 ± 5.78 nmol/ml; p = 0.002, Cohen’s d = 1.3), and an apparent increase in antioxidant capacity (SOD 11.36 ± 2.25 vs. 6.93 ± 2.54 U/ml; p < 0.001, Cohen’s d = 2.0). Furthermore, 6G-IR significantly attenuated morphological damage (MGG score) and suppressed eNOS expression (H-score) compared to the IR group (Cohen’s d = 1.7 and d = 1.4, respectively). These findings provide strong preliminary evidence that 6-Gingerol preserves microcirculatory function through SOD-mediated neutralization of superoxide, thereby preventing peroxynitrite-induced erythrocyte membrane damage. Further power-calculated studies are warranted to explore its clinical translational potential.
