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
This study analyzes data from the National Health and Nutrition Examination Survey (NHANES) to identify factors influencing cognitive performance among the elderly, as measured by the Digit Symbol Substitution Test (DSST). Employing multivariable linear regression, we evaluated the impact of demographic, lifestyle, and health-related factors on cognitive function in U.S. adults aged 60 and older. Our findings indicate that advanced age, particularly in those aged 70-79 and 80 + years, is associated with lower DSST scores. Male gender is linked with reduced cognitive performance, while higher educational attainment appears protective. Lifestyle factors, including current smoking and higher alcohol consumption, negatively impact cognitive outcomes, and excessive sleep duration (over 9 h) is also detrimental. Among health conditions, diabetes, chronic heart failure, and a history of stroke were associated with cognitive declines. Furthermore, increasing severity of depression correlates with lower cognitive function. These results underline the need for comprehensive public health strategies that integrate lifestyle modifications and chronic disease management to maintain cognitive health in older adults.
