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
Introduction: Arteriogenic erectile dysfunction (AED) is the vascular subtype of erectile dysfunction and is closely linked to endothelial dysfunction. The Endothelial Activation and Stress Index (EASIX), calculated from lactate dehydrogenase (LDH), creatinine, and platelet count, has been recognized as a surrogate marker of endothelial injury in several vascular-related conditions. The aim of this study is to explore the association between EASIX and AED. Methods: In this cross-sectional study, 193 men were enrolled, including 94 patients diagnosed with AED and 99 controls. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5), nocturnal penile tumescence and rigidity, and color duplex Doppler ultrasonography. EASIX was calculated as LDH × creatinine/platelet count. Multivariate logistic regression analysis was performed to evaluate the association between EASIX and AED after adjusting for potential confounders. Receiver operating characteristic (ROC) curve analysis was conducted to assess diagnostic performance. Results: EASIX levels were significantly higher in the AED group compared to controls (1.13 [0.72-1.55] vs. 0.79 [0.58-1.01], Conclusion: EASIX was significantly associated with AED and demonstrated moderate diagnostic performance. Prospective studies are warranted to validate its clinical applicability.
