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

backgroundPrior research has consistently shown an association between muscle strength and various metabolic diseases. However, the relationship between muscle strength and cognitive impairment remains elusive.

methodsUsing data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES), we investigated the association between muscle strength and cognitive impairment. We used multivariate logistic regression, restricted cubic spline regression (RCS), and threshold effects to investigate the impact of muscle strength on cognitive function. In addition, we analyzed the correlation between muscle strength and cognitive impairment in subgroups of age, gender, race, education, smoking status, drinking status, hypertension, diabetes, and heart disease.

results2124 participants were ultimately included for further analysis. Multivariate logistic regression, trend testing, and RCS analysis showed a non-linear negative correlation between muscle strength and cognitive impairment. Threshold effect analysis suggests that when muscle strength reaches a certain value, this relationship undergoes significant changes. In the three cognitive function scoring tests, interaction was only observed in the racial subgroup.

conclusionThis study suggests a negative correlation between muscle strength and cognitive function, which may have a threshold effect. Further longitudinal studies are needed to elucidate its potential mechanisms.
