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
Tortuosity of the vasculature poses challenges to mechanical thrombectomy (MT); however, only a few studies have reported the impact of vertebral artery (VA) tortuosity on MT. The present study aimed to investigate the impact of tortuosity of the V1-segment VA on MT in patients with acute vertebrobasilar artery occlusion (AVBAO). The patients diagnosed with AVBAO and treated with MT in the Stroke Center of Xijing Hospital from November 2019 to March 2022 were analyzed retrospectively. According to the tortuosity of V1-segment VA, patients were divided into tortuous (coiling and kinking) and non-tortuous groups (straight, single-arc, and multi-arc). A binary logistic regression model was established to analyze the association between the tortuosity of V1-segment VA and successful reperfusion (mTICI ≥ 2b), neurological improvement at 7 days, favorable and poor outcome at 90 days, and symptomatic intracranial hemorrhage (ICH) within 24 h. After adjustment for age, baseline National Institute of health stroke scale (NIHSS) score and puncture-to-recanalization time, the impact of tortuosity of the V1-segment VA on outcomes was analyzed. After screening, 35 patients were enrolled in this study. The overall rate of successful reperfusion was 74.3% (26/35), and 40% (14/34) patients achieved favorable outcomes at 90 days. Subsequently, 15/35 (42.9%) patients were included in the tortuous group, and the remaining 20 patients comprised the non-tortuous group. After adjustment for age, baseline NIHSS score, and puncture-to-recanalization time, the rate of 90-day favorable outcome in the tortuous group was significantly lower than that of the non-tortuous group (20% vs. 57.9%, P = 0.034), while the rates of reperfusion (80% vs. 73.7%) and 7-day neurological improvement (33.3% vs. 36.8%) were similar between the two groups. The incidence of 24-h symptomatic ICH in the tortuous group was higher than that in the non-tortuous group (26.7% vs. 15.8%), albeit not significantly. In patients with AVBAO, tortuosity of the V1-segment VA was negatively associated with favorable outcomes 90 days after MT.
