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
Objective: This study aimed to evaluate the therapeutic potential of YS-10, a novel flavonoid derivative of icariside II (ICA II), and to explore its mechanism of action in a diabetic rat model of erectile dysfunction (DMED). Methods: Twenty-four male Sprague-Dawley rats were divided into four groups: control, DMED, DMED + ICA II (2.5 mg/kg/day), and DMED + YS-10 (2.5 mg/kg/day). Treatments lasted for 4 weeks followed by a 3-day washout. Erectile function was assessed, and penile tissues were analyzed by histology, immunohistochemistry, ELISA, and Western blot. In vitro, primary corpus cavernosum endothelial cells (CCECs) were treated with advanced glycation end products (AGEs), YS-10, Fer-1 (ferroptosis inhibitor), or ML385 (Nrf2 inhibitor) to evaluate oxidative stress and ferroptosis. Results: In vivo, both YS-10 and ICA II (2.5 mg/kg/day) significantly improved erectile function in diabetic rats, increased smooth muscle content, reduced collagen deposition, and enhanced endothelial marker (CD31) expression in penile tissue ( Conclusion: YS-10 improves erectile function in diabetic rats by reducing oxidative stress and inhibiting ferroptosis via activation of the Nrf2/HO-1/GPX4 pathway. At 2.5 mg/kg/day, YS-10 was effective, well-tolerated, and showed efficacy comparable to ICA II. These findings support its potential as a promising candidate for diabetes-related erectile dysfunction therapy.
