Association of cataract surgery with stroke among older adults in the United States.

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/
objectivesCataract surgery, one of the most frequent conducted surgeries around the world, is associated with cardiovascular diseases. We aim to determine the association of cataract surgery and the risk of stroke.
methodsAdults aged over 65 years old in the National Health and Aging Trends Study were followed 7 years annually. There were 6700 stroke-free participants included at baseline survey. These participants were divided into two groups based on past history of cataract surgery. Demographics and multiple comorbidities were compared between the two groups. We identified newly developed cases of stroke over a 7-year period and performed survival analysis. Cox regression was further performed to yield adjusted hazard ratios.
resultsAmong 6700 elderly participants, 2803 of them had a history of cataract surgery while 3897 of them had not. Over the 7-year follow-up period, the cumulative stroke-free survival rate among the cataract surgery group and the control group were 84.4% versus 88.6% (p < 0.0001, log-rank test). Compared with the control group, elderly with a history of cataract surgery had a higher risk of developing stroke (adjusted HR 1.36, 95% CI 1.03 to 1.79, p = 0.026) after adjusting for multiple covariates. Other significant predictors included age ≥80 years old, having comorbidities with heart disease, lung disease, and dementia. Contrarily, protective factors for further stroke development included higher education and more frequent outdoor activities.
conclusionsOur findings suggest that patients with a history of cataract surgery had a 1.36-fold increased risk of future stroke development.
