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
introductionDespite the diagnostic value of intracavernosal injections (ICI) and penile Doppler ultrasound (PDUS), there remain barriers to widespread clinical adaptation of these methods. The study aimed to evaluate the practice patterns of utilization of ICI and PDUS in the assessment of erectile dysfunction (ED) and Peyronie's disease (PD).
methodsUsing the TriNetX database (Cambridge, MA, USA), adult (≥18 years) male patients with a diagnosis of ED on oral phosphodiesterase-5 (PDE5) inhibitors were identified. Current Procedural Terminology codes were utilized to identify patients who underwent further evaluation with ICI or PDUS, as well as penile prosthesis placement after PDUS. A second cohort was analyzed, identifying patients with a diagnosis of PD who underwent ICI or PDUS, and those who subsequently underwent PD treatment.
resultsAmong 104 healthcare organizations, 52,227,262 adult males were screened for ED and PD. 1,689,907 (3.2%) patients had ED and 66,390 (0.1%) patients had PD. Among ED patients, there were 6508 (0.4%) who subsequently went on to receive penile prosthesis. Amongst ED patients, only 23,836 (1.4%) and 8548 (0.5%) patients underwent workup with ICI or PDUS. The number of patients who subsequently received a prosthesis after ICI and PDUS workup was 4680 (19.6%) and 868 (10.1%), respectively. Amongst PD patients, 2960 (4.5%) and 4972 (7.4%) underwent workup with ICI and PDUS, respectively.
conclusionWe recognize that ED and PD are challenging disease processes with complicated diagnostic workup involved. We recommend that providers be knowledgeable about counseling patients and even consider referring motivated patients to high-volume referral centers for definitive treatment.
