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 patients with stroke with large-vessel occlusion and extensive ischemic change denoted by low Alberta Stroke Programme Early Computed Tomography Score (ASPECTS), the role of bridging thrombolysis before endovascular thrombectomy (EVT) is still to be determined. We aimed to examine the impact of ischemic change on clinical outcomes and how this is modified by bridging thrombolysis in patients treated with EVT. Methods: Consecutive patients undergoing anterior circulation EVT from a prospectively collected registry were included in this retrospective analysis. ASPECTS was evaluated from baseline noncontrast computed tomography scans with lower scores indicating larger areas of ischemic change. Outcome measures included symptomatic intracranial hemorrhage and functional independence (modified Rankin Scale score, 0-2) at day 90. Multivariable logistic regression models with interaction terms between ASPECTS and bridging thrombolysis were created. ASPECTS was treated as numeric variable in the primary analysis and trichotomized (ASPECTS ≤5, 6-8, 9-10) in a sensitivity analysis. Results: A total of 872 patients undergoing EVT (384 women, mean±SD age of 67±15, baseline National Institute of Health Stroke Scale 16 [interquartile range, 11-20]) were included. A total of 549 (63%) patients were transferred from primary stroke centers for EVT and 436 (50%) received bridging intravenous thrombolysis with alteplase. On baseline computed tomography scan, median [interquartile range] ASPECTS was 8 [7-9], with 408 (47%) having minimal (ASPECTS 9-10), 376 (43%) moderate (ASPECTS 6-8), and 88 (10%) extensive (ASPECTS ≤5) ischemic change. With decreasing numeric ASPECTS, the probability of functional independence reduced (ASPECTS main effect adjusted odds ratio, 1.36 [95% CI, 1.23-1.52]; Conclusion: In a cohort of patients undergoing EVT where most were transferred from a primary stroke center, ischemic change was associated with decreased probability functional independence, but this effect was attenuated with bridging thrombolysis. These results suggest that patients with large areas of ischemic change may still benefit from the earliest possible reperfusion afforded by bridging thrombolysis.
