Factors Associated With Improved Technical Outcomes When Using 0.068- to 0.074-Inch Aspiration Catheters: Analysis From a Multicenter Retrospective Cohort.
Article in Stroke (Hoboken, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: In addition to enlarging the catheter tip diameter, recent aspiration catheters were designed with a novel angled-tip design. We aimed to evaluate the efficacy of new-generation angled-tip aspiration catheters in comparison to commonly used straight-tip large-bore aspiration catheters. Methods: We performed a multicenter retrospective analysis of consecutive cases with M1 occlusion treated with aspiration thrombectomy from July 2016 to February 2021. Patients were divided into 2 cohorts: those in whom a 0.071-inch angled-tip catheter was used and those in whom a 0.068- to 0.074-inch flat-tip catheter was used. Results: A total of 384 patients were identified. The angled-tip catheter was used in 129 (33.6%) patients, whereas 255 (66.4%) patients were treated with flat-tip catheters. There was no significant difference in age, sex, baseline modified Rankin scale score, side of occlusion, initial National Institutes of Health Stroke Scale score, time from last known normal to access, or rate of intravenous recombinant tPA (tissue-type plasminogen activator) administration. Use of the angled-tip reperfusion catheter was associated with average 5-minute faster time to Thrombolysis in Cerebral Infarction 2B or better (22.13±21.05 versus 27±24.54 minutes; Conclusions: We report a multicenter, retrospective review of patients treated with current generation large-bore aspiration catheters. Angled-tipped catheters were associated with shorter times to Thrombolysis in Cerebral Infarction 2B and final reperfusion. There were no differences in 90-day modified Rankin scale score, rates of intracranial hemorrhage, or complications.
