1 · What the graph read from it

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.

2 · The registry

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 risk of dementia in patients with ischemic stroke and early cardiovascular complications (i.e., stroke-heart syndrome [SHS]) remains underexplored.

methodsPatients with first-ever ischemic stroke in Hong Kong between 2005 and 2020 were included. Multivariable Fine-Gray competing risk analysis was performed after 1:1 propensity score matching to evaluate the association between SHS and the risk of dementia.

resultsOf the 130,605 included patients with ischemic stroke, 12,696 (9.7%) patients developed SHS. Patients with SHS had a 19% increased risk of dementia compared to those without SHS at 1 year post-stroke, driven mainly by vascular dementia. This increased risk gradually declined and became non-significant after 3 years post-stroke. Appropriate antithrombotic therapy and comorbidities optimization were associated with a 32% reduced dementia risk in patients with SHS. DISCUSSION: SHS is associated with an increased risk of incident dementia. Appropriate antithrombotic therapy and comorbidities optimization post-stroke may reduce this heightened risk of cognitive impairment. HIGHLIGHTS: Association between stroke-heart syndrome (SHS) and dementia was evaluated in a population-based cohort. Development of SHS associated with a 19% increased 1 year risk of dementia. The increased risk of dementia gradually declined with each year of follow-up. Integrated post-stroke management may reduce this heightened risk of cognitive impairment.
