Aggressive Angiomyxoma in the Anus of Elderly Male.

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
Aggressive angiomyxoma (AAM) is a rare mesenchymal tumor characterized by local invasion and a high recurrence rate, primarily affecting the pelvic-perineal region in women. It is extremely rare in men. Although male-onset cases are typically reported in the scrotum or buttocks, there have been no previously reported cases involving the anus. We report the first such case in a 71-year-old man initially diagnosed with prolapsed internal hemorrhoids (Goligher grade IV). The patient underwent surgical treatment; however, histological analysis of the specimen unexpectedly revealed AAM, with positive findings for CD34 (+), desmin (+), and partially positive ER (ER [partial +]). The postoperative course was complicated by hemorrhage, requiring hemostasis via vascular embolization. Despite the high recurrence rate of AAM, the patient has remained disease-free for over five years.
