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
Older adults (≥60 years) are at high risk for cognitive impairment, yet the impact of varying levels of alcohol consumption on cognitive function in this population remains unclear. This study aims to evaluate the effect of alcohol consumption on cognitive function among older adults in the United States. Researchers obtained data from 3632 participants aged 60 years and older from the 2011 to 2014 National Health and Nutrition Examination Survey. Alcohol consumption was assessed using a questionnaire, while cognitive function was evaluated using the Word Learning and Recall module from the Consortium to Establish a Registry for Alzheimer Disease, the Animal Fluency Test, and the Digit Symbol Substitution Test. The relationship between alcohol consumption and cognitive function was analyzed using weighted multivariable linear regression and stratified analysis based on key covariates. Fully adjusted Model 3 indicated that, compared to nondrinkers, light drinkers had an increase in cognitive function scores by 0.44 (β = 0.44, 95% confidence intervals [CI]: 0.20-0.67; P < .001), while moderate and heavy drinkers experienced a decline in cognitive function scores by 0.62 (β = -0.62, 95% CI: -0.89 to -0.34; P < .001) and 0.97 (β = -0.97, 95% CI: -1.23 to -0.62; P < .001), respectively. Stratified analysis revealed that heavy drinking had a more detrimental effect on cognition among individuals aged 70 and older, women, those with less than a high school education, and those with diabetes, hypertension, or a history of stroke. In older adults (≥60 years) in the United States, heavy alcohol consumption is associated with a decline in cognitive scores, particularly among those aged 70 and older, women, individuals with less than a high school education, and those with diabetes, hypertension, or a history of stroke.
