Intra-cranial aneurysm treatment with contour or WEB - a single center comparison of intervention times and learning curves.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 purposeTreating aneurysms with intra-saccular flow disruption is a feasible alternative to coil-embolization. Besides the established WEB device, the novel Contour Neurovascular System has emerged as a potentially easier alternative regarding sizing and deployment. We report the learning curve experienced at our center from the first 48 patients treated with Contour and compared it with 48 consecutive WEB cases.MethodsBoth groups were compared concerning intervention time, sizing failures leading to device changes and radiation dose. Additionally, we analyzed potential learning effects by comparing the first 24 Contour cases with our last 24 Contour cases and WEB cases respectively.ResultsPatient demographics, acute vs. incidental cases and aneurysm localization were comparable in both groups. The deployment time was faster in our 48 Contour cases (median: 22.0 ± 17.0 min), than in the WEB group (median: 27.5 ± 24.0 min). Total intervention time was similar for Contour (median: 68.0 ± 46.9 min) and WEB cases (median: 69.0 ± 38.0 min). Device implantation times in our WEB cases were slightly shorter in the later cases (median: 25.5 ± 24.1 min) than in the earlier (median: 28.0 ± 24.4 min) cases. In the Contour cohort, deployment times were similar for the first 24 cases (median: 22.0 ± 14.5 min) and the final 24 (median: 22.0 ± 19.4 min). Radiation dose was lower in the Contour group (1469.0 ± 1718 mGy*cm
