Sclerosing angiomatoid nodular transformation of the spleen in an 18-year-old man: a case report.

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
Sclerosing angiomatoid nodular transformation (SANT) is a rare benign vascular lesion of the spleen, particularly uncommon in adolescents. We report the case of an 18-year-old man with an incidentally detected splenic mass showing a characteristic spoke-wheel enhancement pattern. Although a benign lesion was suspected, malignancy could not be excluded, and laparoscopic splenectomy was performed. Histopathological examination confirmed SANT, and the postoperative course was uneventful. A review of previously reported cases in patients younger than 20 years revealed a median age of 8.5 years, with abdominal pain in 76.9% and nonspecific laboratory abnormalities in 45.5% of cases. Partial splenectomy was performed in 46.7% of patients; however, tumors located at the splenic hilum were consistently treated with total splenectomy. SANT in adolescents is rare and difficult to diagnose preoperatively. Tumor location, particularly when located at the splenic hilum, may be a key factor in determining surgical strategy.
