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
Introduction and importance: Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder with an incidence of about 2-5:100 000. It is characterized by the triad of cutaneous hemangiomas, soft tissue or bone hypertrophy, and venous malformations. Gastrointestinal (GI) involvement in KTS, although uncommon, can lead to severe complications such as profuse GI bleeding. Our case highlights the challenges and management strategies of a patient with KTS. Case presentation: A 5-year-old child presented with rectal bleeding since birth, accompanied by swelling and bluish discoloration on left flank, and multiple varicose veins on left leg. Examination revealed small hemangiomatous lesions scattered along the torso and trunk. Barium enema showed diffuse mucosal irregularity with polypoidal filling defects in the rectum and sigmoid colon. Doppler ultrasound revealed slow-flow vascular lesions in the left flank and leg without arteriovenous communication. Computed tomography (CT) scan showed diffuse cavernous hemangiomas in the descending colon, sigmoid colon, and rectum. Histopathology demonstrated numerous dilated, irregular vascular channels with calcification and hemosiderin-laden macrophages. Clinical discussion: GI tract cavernous hemangiomas can cause chronic bleeding and anemia, necessitating careful evaluation. Imaging modalities like CT and Doppler ultrasound are crucial for assessing vascular lesions. Surgical interventions, including partial proctocolectomy and colorectal anastomosis, effectively control bleeding and improve outcomes. A multidisciplinary approach is essential for managing such cases. Conclusion: This case underscores the importance of multidisciplinary management in KTS with GI bleeding. Effective diagnostic imaging and surgical treatment are key to managing severe complications and achieving successful outcomes. Long-term follow-up is crucial to monitor for recurrence and residual lesions.
