Outcomes of Endovascular Treatment in Patients With Vertebrobasilar Artery Occlusion Beyond 24 Hours.

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
Importance: The efficacy and safety of endovascular thrombectomy (EVT) plus best medical treatment (BMT) for vertebrobasilar artery occlusion beyond 24 hours remain uncertain. Objective: To evaluate outcomes associated with EVT in patients treated beyond 24 hours after last known well time due to vertebrobasilar artery occlusion. Design, Setting, and Participants: This multicenter, prospective cohort study enrolled patients between 2019 and 2024 from 11 comprehensive stroke centers across China. Eligible patients with vertebrobasilar artery occlusions treated beyond 24 hours after the estimated onset were included. Exposures: Patients were categorized into 2 groups: those who underwent EVT plus BMT and those who received BMT alone. Main Outcomes and Measures: The primary outcome was good functional status (modified Rankin Scale score, 0-3) at 90 days. Safety outcomes included symptomatic intracranial hemorrhage within 24 hours and 90-day mortality. Results: Among 202 patients with vertebrobasilar occlusion (158 male [78.2%]; median [IQR] age, 64.0 [56.2-70.0] years), 101 patients received EVT plus BMT and 101 patients received only BMT. The median (IQR) posterior circulation Acute Stroke Prognosis Early Computed Tomography Score was 8 (8-9), and the median (IQR) of time of onset to admission was 48 (24-96) hours. In the primary analysis using propensity score matching, 71 patients with EVT plus BMT had a higher rate of a good functional outcome at 90 days compared with 71 patients receiving BMT alone (41 patients [57.7%] vs 32 patients [45.1%]; adjusted risk ratio [aRR], 1.35 [95% CI, 1.02-1.79]). EVT plus BMT compared with BMT alone showed lower mortality (9 patients [12.7%] vs 20 patients [28.2%]; aRR, 0.27 [95% CI, 0.08-0.81]); differences in rates of symptomatic intracranial hemorrhage were not statistically significant (4 patients [5.6%] vs 0 patients; P = .13). A similar advantage in functional outcome for EVT plus BMT (aRR, 1.33 [95% CI, 1.04-1.71]) was observed in the inverse probability of treatment weighting analysis. Conclusions and Relevance: In this study, EVT plus BMT was associated with improved functional outcomes and survival rates at 90 days and a nonsignificant but numerically higher frequency of symptomatic intracranial hemorrhage than BMT alone in patients treated beyond 24 hours after last known well time. These findings suggest that randomized clinical trials comparing EVT with BMT in patients with acute vertebrobasilar artery occlusion are warranted.
