Predictors and outcomes of ischemic stroke in reversible cerebral vasoconstriction syndrome.
Observational study in Journal of neurology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionThe clinical factors predisposing to ischemic stroke in reversible cerebral vasoconstriction syndrome (RCVS) are unclear. In this observational cross-sectional study, we aimed to evaluate the risk factors and clinical outcomes associated with the development of ischemic stroke in patients with RCVS.
methodsWe utilized the Nationwide Readmissions Database 2016-2017 to identify all hospitalizations with RCVS, with or without acute ischemic stroke. Independent predictors of and clinical outcomes associated with ischemic stroke were analyzed using logistic regression.
resultsAmong 1065 hospitalizations for RCVS (mean ± SD age 49.0 ± 16.7 years, female 69.7%), 267 (25.1%) had ischemic stroke. Patients with ischemic stroke were more likely to have hypertension (OR 2.33, 95% CI 1.51-3.60), diabetes (OR 1.81, 95% CI 1.11-2.98), and tobacco use (OR 1.64, 95% CI 1.16-2.33) and were less likely to have a history of migraine (OR 0.56, 95% CI 0.35-0.90). Ischemic stroke was associated with higher odds of cerebral edema (OR 3.15, 95% CI 1.31-7.57) and respiratory failure (OR 2.39, 95% CI 1.28-4.44). Patients with ischemic stroke also had longer hospital stay by a mean duration of 6.7 days, P < 0.001, higher hospital charges by a mean of $72,961, P < 0.001, and a higher likelihood of not being discharged to home (OR 3.57, 95% CI 2.39-5.33). They had higher in-hospital mortality rate; however, the difference was not statistically significant.
conclusionIschemic stroke affects nearly 25% of patients with RCVS and is associated with adverse clinical outcomes. RCVS patients with cerebrovascular risk factors might have a higher predisposition for developing ischemic lesions during the disease process.
