Fournier's Gangrene Following Hydrogel Spacer-related Rectal Ulcer and Fistula in a Patient Undergoing Radiation Therapy for Prostate Cancer.

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
Hydrogel spacers are commonly used to reduce rectal toxicity during radiation therapy for prostate cancer. Although generally safe, rare, serious complications may occur. We report the case of a man with diabetes and renal failure who developed a refractory rectal ulcer and fistula five months after spacer placement, followed by Fournier's gangrene. The patient recovered following surgical drainage and antibiotic therapy. This is the first reported case of Fournier's gangrene following hydrogel spacer insertion. Spacer-related rectal wall infiltration might have contributed to this finding. Clinicians should recognize such adverse events and consider early intervention in high-risk patients presenting with hematochezia or perineal symptoms.
