Simplified Assessment of Erectile Dysfunction in Adult Men With Sickle Cell Disease: A Cross-Sectional Validation Study.
Article in Cureus, 2025. 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
objectiveTo estimate the prevalence of erectile dysfunction (ED) and assess the diagnostic performance of simplified tools - the Erection Hardness Score (EHS), the Massachusetts Male Aging Study (MMAS) single-item scale, and a visual analog "Erectometer" - against the International Index of Erectile Function-5 (IIEF-5) among adult men with sickle cell disease (SCD).
methodsCross-sectional validation study including 33 adult men with confirmed SCD followed at a regional reference center in Bahia, Brazil (July-December 2021). Sociodemographic, clinical, and laboratory data (total and free testosterone, luteinising hormone (LH), follicle stimulating hormone (FSH), estradiol, ferritin) were collected. Erectile function was assessed using IIEF-5 (reference standard), EHS, MMAS single-item, and the Erectometer. Receiver operating characteristic (ROC) curves and area under the curve (AUC) quantified diagnostic accuracy.
resultsMedian age was 35 [IQR 28-48] years; 33% reported prior ischemic priapism. By IIEF-5, 15/33 (45.5%) had moderate-severe ED (≤16). AUCs against IIEF-5 were 0.85 for EHS, 0.82 for MMAS, and 0.90 for the Erectometer (all p<0.001), with sensitivities ≥ 81% and specificities ≥ 79%.
conclusionED is frequent in Brazilian adults with SCD. Brief instruments (EHS, MMAS single-item, Erectometer) show excellent agreement with IIEF-5 and appear suitable for routine screening, potentially enabling earlier multidisciplinary care.
