Matched-Pair Analysis of Patients With Large-Vessel Occlusions Undergoing Thrombectomy Using Single-Plane Versus Biplane Angiography.

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
backgroundThe Mechanical Thrombectomy Global Access for Stroke study demonstrated that access to mechanical thrombectomy (MT) is <3% of demand, with severe disparities across urbanization and income levels. Although biplane angiography is the standard, single-plane systems may offer a cost-effective alternative. We conducted a propensity-matched analysis comparing the procedural and clinical outcomes of MT performed in single-plane versus biplane angiography suites.
methodsAll consecutive stroke MT cases performed at 3 centers (2 single plane and 1 biplane) between 2018 and 2024 were included. Outcomes assessed included rates of first-pass effect (modified Thrombolysis in Cerebral Infarction score ≥2b on first pass), successful reperfusion (final modified Thrombolysis in Cerebral Infarction score ≥2b), time to reperfusion, complication rates, postprocedural symptomatic intracranial hemorrhage, and good clinical outcome (modified Rankin Scale score 0-2) at discharge, 30 days, and 90 days.
resultsA total of 51 thrombectomies were performed in single-plane suites, and 367 were performed in biplane suites. After propensity matching, 100 patients (50 in each group) were included. In a multivariable analysis, the type of angiography suite was not significantly associated with successful reperfusion (odds ratio, 3.84 [95% CI, 0.22-68.4];
conclusionsThis propensity score-matched analysis comparing MT for large-vessel occlusion in single-plane versus biplane angiography suites demonstrated no statistically significant differences in procedural and clinical outcomes or safety measures. These results indicate that MT using single-plane angiography suites can serve as a viable alternative for treating proximal large-vessel occlusions within the anterior circulation in areas where establishing a full biplane suite is not feasible.
