5F SOFIA intermediate catheter in the treatment of acute ischemic stroke: A retrospective observational study.
Observational study in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe herein report our experience with the 5F SOFIA (Soft Torqueable catheter Optimized for Intracranial Access) intermediate catheter for endovascular treatment of patients with acute ischemic stroke (AIS) both in distal middle vessel occlusions (DMVOs) and in large vessel occlusions (LVOs) with unfavorable anatomy.
methodsRecords of forty-seven patients undergoing endovascular thrombectomy with 5F SOFIA between September 2020 and March 2022 were retrospectively reviewed. Patients' demographic data, clinical presentation, treatment details, and complications were recorded from the medical record. The primary outcomes were successful revascularization (modified treatment in cerebral ischemia, mTICI ≥2b) and good clinical outcome at 3 months (modified rankin scale, mRS 0-2). Secondary outcomes were complication rates and switch to alternative techniques. Our institutional review board approved this study.
resultsForty-seven patients with AIS treated with 5F SOFIA were examined. In eighteen (38%) cases the occlusion was located on a large vessel while in 29 (61.7%) on a distal-medium vessels. Median national institutes of health strokes scale (NIHSS) score was 16 at admission. Successful revascularization to mTICI 2b-3 was achieved in 14 of 18 patients (77.7%) with LVOs and in 24/29 cases with DMVOs (82.7%) respectively. mRS score 0-2 at three months (3 months-mRS 0-2) was 66.6% for LVOs and 68.9% in DMVOs respectively. Symptomatic intracranial hemorrhage (SICH) occurred in 2 (4.2%) patients.
conclusion5F SOFIA intermediate catheter could be a safe and effective treatment for AIS and a viable alternative to 6 F conventional intermediate catheters in selected cases.
