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
introductionType IIIa endoleak (TIIIaEL) is a serious complication following endovascular aneurysm repair, requiring immediate reintervention. We describe a case of TIIIaEL with proximal component separation in a patient treated with an AFX2 endograft. PRESENTATION OF CASE: TIIIaEL and an enlarged aneurysm were observed in an 87-year-old man 30 months after endovascular repair of an abdominal aortic aneurysm using an Endurant aortic extension cuff and an AFX2. The initial aneurysm diameter was 58 mm. Following surgery, the patient was discharged without complications. Follow-up was conducted with computed tomography every 6 months. The aneurysm decreased by 1-2 mm at the 24-month postoperative visit but subsequently showed gradual disconnection of the junction, leading to a diagnosis of aneurysm enlargement. After TIIIaEL, the aneurysm diameter was 62 mm. Urgent reintervention was performed through endovascular treatment instead of open surgery. Two non-bare VELA Proximal Endografts (A34-34/C100V, Endologix, Irvine, CA, USA) and one Excluder aortic extender (PLA280300J, W. L. Gore & Associates Inc., Flagstaff, Arizona, USA) were inserted into the gap between the proximal cuff and main body. No endoleaks were observed. The aneurysm diameter decreased without complications. No recurrence was documented after 1 year. The patient is progressing without noticeable symptoms. DISCUSSION: The AFX-aortic extension cuff junction may become disconnected due to self-expanding movement and linear forces, causing TIIIaEL. Devices from different manufacturers may have contributed to the occurrence of TIIIaEL.
conclusionModular device overlaps should be as long as possible, and close postoperative monitoring is necessary when this device is used.
