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 7-year-old female intact, black-and-white ruffed lemur (Varecia variegata) presented for acute anorexia, lethargy, and abnormal behavior. Initial radiographs were concerning for gastrointestinal ileus. Abdominal ultrasonography identified bilateral periovarian masses and a moderate volume of echogenic peritoneal effusion; no definitive blood flow was seen within the masses on Color Doppler. Bilateral ovariectomy was performed, and histopathology confirmed bilateral ovarian hematomata and hemoabdomen due to an idiopathic arteriopathy. The patient recovered with no significant postoperative complications. This is the first reported case of spontaneous bilateral ovarian hemorrhage in a black-and-white ruffed lemur, secondary to idiopathic arteriopathy, reported within the veterinary literature.
