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
Purpose: The association between the Alberta Stroke Programme Early CT Score (ASPECTS) and intracranial hemorrhage (ICH) in acute ischemic stroke (AIS) patients undergoing thrombolysis remains unclear. This study aimed to determine the relationship between ASPECTS and thrombolysis-associated outcomes, focusing on symptomatic (sICH) and asymptomatic (aICH) ICH. Patients and methods: AIS patients with middle cerebral artery (MCA) territory treated with thrombolysis were enrolled. Patients were categorized into favorable (8-10) and unfavorable (7 or less) ASPECTS. The primary outcomes were sICH and aICH. Secondary outcomes included ICH management, modified Rankin Scale (mRS), and mortality. Multivariable logistic regression analysis evaluated the risk of unfavorable ASPECTS and its association with study outcomes. Results: We included 622 patients (mean age 66.1 ± 13.5 years; 50.5% male); 95 (15.3%) had unfavorable ASPECTS. Patients with unfavorable ASPECTS had higher sICH but not aICH (21.1% vs 4.9%, P < 0.001 and 16.9% vs 17.3%, P = 1.00). Unfavorable ASPECTS was associated with sICH (adjusted odds ratio 5.1; 95% confidence interval 2.7-9.7, P < 0.001). Factors associated with lower ASPECTS included age ≥ 65 years, body weight < 60 kg, atrial fibrillation, onset-to-needle time ≥ 120 minutes, and anemia. Patients with lower ASPECTS had higher mortality and unfavorable mRS (>2) at discharge, 14 days, and 90 days (74.7% vs 50.1%, P < 0.001 for 90-day mRS >2). Conclusion: ASPECTS is a simple tool to predict thrombolysis-associated sICH but not aICH. Patients with unfavorable ASPECTS are at higher risk of complications and poor functional outcomes. Alternative treatments, such as mechanical thrombectomy, might be advisable for these patients.
