Impact of prodromal symptoms on the prognosis of patients with basilar artery occlusion treated with mechanical thrombectomy.

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
introductionEven with reperfusion therapies, the prognosis of patients with basilar artery occlusion (BAO) related stroke remains poor. We aimed to test the hypothesis that the presence of prodromal symptoms, an easily available anamnestic data, is a key determinant of poor functional outcome. PATIENTS AND
methodsData from patients with BAO treated in Lille, France, with mechanical thrombectomy (MT) between 2015 and 2021 were prospectively collected. The presence of prodromal symptoms was defined by previous transient neurological deficit or gradual progressive clinical worsening preceding a secondary sudden clinical worsening. We compared the characteristics of patients with and without prodromal symptoms. We built multivariate logistic regression models to study the association between the presence of prodromal symptoms and functional (mRS 0-3 and mortality), and procedural (successful recanalization and early reocclusion) outcomes.
resultsAmong the 180 patients, 63 (35%) had prodromal symptoms, most frequently a vertigo. Large artery atherosclerosis was the predominant cause of stroke (41.3%). The presence of prodromal symptoms was an independent predictor of worse 90-day functional outcome (mRS 0-3: 25.4% vs 47.0%, odds ratio (OR) 0.39; 95% confidence interval (CI) 0.16-0.86) and 90-day mortality (OR 2.17; 95% CI 1.02-4.65). Despite similar successful recanalization rate, the proportion of early basilar artery reocclusion was higher in patients with prodromal symptoms (23.8% vs 5.6%, DISCUSSION AND
conclusionMore than one third of BAO patients treated with MT had prodromal symptoms, especially patients with large-artery atherosclerosis. Clinicians should systematically screen for prodromal symptoms given the poor related functional outcome and increased risk of early basilar artery reocclusion.
