Evaluation of cavernosal oxidative biomarkers following radial Li-ESWT in vasculogenic erectile dysfunction.
Article in World journal of urology, 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
purposeVasculogenic erectile dysfunction (ED) is associated with endothelial dysfunction and oxidative stress. This study evaluated the clinical efficacy of radial-type low-intensity extracorporeal shockwave therapy (Li-ESWT) and its effects on cavernosal oxidative stress biomarkers.
methodsIn this prospective study, 48 men with vasculogenic ED underwent 12 sessions of radial-type Li-ESWT. Erectile function was assessed at baseline, 1 month, and 6 months using the International Index of Erectile Function-Erectile Function domain (IIEF-EF) and Erection Hardness Score (EHS). Cavernosal blood samples were collected before treatment and one week after completion to measure superoxide dismutase (SOD), ischemia-modified albumin (IMA), thiol-disulfide homeostasis, and glutathione redox status.
resultsAt 6 months, 43.8% of patients achieved a clinically meaningful improvement in IIEF-EF. Both IIEF-EF and EHS scores improved significantly at 1 and 6 months (p < 0.001). In exploratory multivariable logistic regression analysis, prior PDE5i responsiveness remained independently associated with clinically meaningful improvement (OR 5.59, 95% CI 1.24-25.23; p = 0.025), whereas HbA1c did not retain significance. No significant changes were observed in SOD, IMA, or glutathione redox status. Borderline thiol-disulfide alterations observed in unadjusted analyses did not remain significant after correction for multiple comparisons and were not associated with clinical outcomes.
conclusionRadial-type Li-ESWT was associated with clinically meaningful improvements in erectile function in men with vasculogenic ED. However, no robust oxidative biomarker changes were observed in cavernosal blood following treatment.
