Intravenous thrombolysis therapy and dementia risk in acute ischemic stroke patients: A retrospective cohort study in Taiwan.
Article in Journal of Alzheimer's disease reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Intravenous thrombolysis (IVT) is the standard treatment for acute ischemic stroke (AIS) to improve functional outcomes. Furthermore, AIS is an important risk factor for dementia. Limited evidence has shown the long-term benefit of IVT on dementia in Western countries. Objective: We aim to investigate the association between IVT and the risk of dementia in acute ischemic stroke patients in Asian population. Methods: A retrospective cohort study using medical records from a medical center in Taiwan between 2017 and 2022 was conducted. We included acute ischemic stroke patients aged over 55 years old who had not previously been diagnosed with dementia. The primary outcome was incident dementia ascertained through dementia diagnosis in medical records. The inverse probability of treatment-weighted Cox proportional hazard models were used to estimate the association between IVT and incident dementia. Results: A total of 1471 patients with AIS were included. 939 (63.8%) were male, and the mean age was 70.7 Conclusions: The IVT was associated with lower risk of dementia, although not statistically significant, in reducing the incidence of dementia in Asian patients with ischemic stroke. Studies with larger sample sizes will be needed in the future.
