1 · What the graph read from it

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.

2 · The registry

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

Background: The combination of Intracavernosal Injection (ICI) and Color Doppler Duplex Ultrasonography (CDDU) has emerged as a novel approach for evaluating erectile dysfunction (ED) in recent years. Aim: To evaluate the diagnostic value of multi-modal ultrasound integrated with ICI in patients with ED concomitant with penile curvature. Methods: Eighty-two ED patients were prospectively enrolled in this observational study between April 2021 and February 2025. Multimodal ultrasound, including high frequency ultrasound, CDDU, and shear wave elastography were used to evaluate the penile hemodynamic and structural parameters pre- and post-ICI of Papaverine Hydrochloride. The peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) of the corpus cavernosum artery and SWE-derived Young's modulus values (YM) of the corpus cavernosum were examined. Participants were stratified by curvature presence, with subgroup analyses by different angle (<15°, 15-30°, 31-60°, >60°) and different direction (ventral/lateral, left/right). Outcomes: The differences of penile hemodynamic and structural parameters pre- and post-ICI of all ED patients, and different subgroups of patients with penile curvature were evaluated. Results: (1) Eighty-two men with a median age of 34 (21-67) years were evaluated, including 34 patients (41.46%) diagnosed as ED with penile curvature and 48 patients (58.54%) diagnosed as ED without penile curvature. (2) Using High-frequency ultrasound, Peyronie's disease was detected in 8 patients (9.76%). (3) Following ICI, compared to pre-ICI measurements, both groups exhibited significant increases in PSV ( Clinical Implications: We provide a non-invasive, reproducible method for the integrated assessment of ED complicated with penile curvature by multi-modal ultrasound combined with ICI, and correlate pre-intervention biomechanical and vascular profiles with post-erection anatomical outcomes in ED patients. Strengths & Limitations: The strength of the study lies in its unique approach to evaluate patients with ED concomitant with penile curvature, making the clinical evaluation more complete and precise. However, the limited sample size restricts generalizability and further research. Conclusion: Multi-modal ultrasound combined with ICI provides a non-invasive, reproducible method for the integrated assessment of ED complicated with penile curvature.
