Endovascular Treatment of Wide-Neck Intracranial Aneurysms Using the Novel Contour Neurovascular System: 5-Year Follow-up.
Article in AJNR. American journal of neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
background and purposeThe Contour neurovascular embolization device is a novel way to treat wide-neck bifurcation aneurysms (WNBA), which often pose considerable treatment challenges. In this study, we aim to evaluate the efficacy and safety profile of this device. MATERIALS AND
methodsProspective clinical and radiologic data were collected for all patients treated with the Contour device at our center, between January 2017 and December 2018. All patients were treated electively, and aneurysms were unruptured.
resultsFourteen patients were recruited, and the device was successfully deployed in 11 patients. All patients were women with a mean age of 65 years. Four basilar tip, 2 internal carotid, 3 middle cerebral, 1 anterior communicating, and 1 superior cerebellar artery aneurysms were treated. The mean aneurysmal size was 6 mm (width) × 7.6 mm (height), with 4.1 mm neck. Follow-up imaging included DSA, MRA, and CTA. For the 9 patients available at year 2 follow-up, 5 showed improved occlusion class over time with 8 of 9 having adequate occlusion defined by class 1 and 2 of the Raymond-Roy (R-R) classification system. Eight patients were available for 3-year follow-up: 7 patients had stable occlusion class including 3 patients with stable complete occlusion (R-R class 1). One patient had worsening of R-R occlusion class from 1 to 2 and subsequently presented with acute subarachnoid hemorrhage. Follow-up data 5 years after implantation were available for 8 patients (including the ruptured and re-treated patient): 7 patients had adequate occlusion (R-R class 1 and 2), however, 1 patient had worsened from R-R class 1 to R-R class 2. Four patients had complete occlusion.
conclusionsResults demonstrate progressive occlusion of wide-neck aneurysms over the first 2 years, but we have also demonstrated worsening of R-R occlusion class in some aneurysms that were previously completely occluded. Our results suggest that the Contour device is a good option in WNBA, however, it appears that patients must be followed up for a minimum of 5 years.
