Cognitive Magnetic Resonance Imaging-Transperineal Ultrasound Fusion Prostate Biopsy with Use of a Urinary Catheter After Abdominoperineal Resection: A Novel Technique and Literature Review.
Article in Research and reports in urology, 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
A standard prostate biopsy can be performed via a transrectal or transperineal approach using a transrectal ultrasound probe, but not in patients without a rectum. These patients pose a diagnostic challenge to urologists in terms of prostate cancer detection. We report use of a novel technique for cognitive magnetic resonance imaging (MRI)-transperineal ultrasound fusion prostate biopsy with a urinary catheter in two patients without a rectum after abdominoperineal resection. In both cases, a urinary catheter was inserted and clamped after injection of 250 mL of sterile saline into the bladder to improve visualization of the prostate. The inflated catheter balloon was placed to the level of the bladder neck to identify the base of the prostate. Cognitive MRI-transperineal ultrasound fusion biopsy was performed on the MRI-defined lesions after confirmation of anatomic landmarks, including the urethra and base of the prostate. Systemic 8-core biopsies were also obtained. In both patients, the targeted lesion was diagnosed as prostate cancer.
