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 report our initial experience on the use of the Walrus, a new generation balloon guide catheter (BGC) capable of accommodating large bore aspiration catheters for patients undergoing endovascular stroke thrombectomy for large vessel occlusion with a particular focus on procedural aspects related to the vascular anatomy, recanalisation efficacy and complications.MethodsThis is a retrospective, site-adjudicated, two-centre study on consecutive patients with anterior circulation large vessel occlusion treated with the Walrus BGC. Baseline characteristics and procedural and clinical outcomes were analysed.ResultsBetween July 2023 and January 2024, we recruited 300 participants (mean age 69.5 ± 15 years; 132 (44%) females). The mean admission NIHSS was 15.8 ± 6.5, and the mean ASPECTS was 7.6 ± 1.9. Combined stent-retriever and aspiration first-line thrombectomy technique was performed in 235 patients (79%). The Walrus BGC was successfully navigated to the ICA in 99.7% of patients. Near complete-complete recanalisation (eTICI2c-3) was achieved in 75.4% of patients, and the eTICI2b-3 rate was 92.2%. First-pass effect (eTICI2c-3) was achieved in 49% of patients, and the modified first-pass effect (eTICI2b-3) was 65.9%. No significant difference in the arterial puncture-to-guide catheter placement time across the three different arch types (
