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

purposeThis study initially conducted a cross-sectional analysis to examine the association between total testosterone (TT), uric acid, and Klotho. The investigation examined whether uric acid mediates the association between TT and Klotho in males.

methodsBased on data from the National Health and Nutrition Examination Survey (NHANES) 2013-2016, this study performed weighted multivariable-adjusted linear regression to evaluate the association between TT, uric acid, and α-Klotho. Then, mediation analysis was conducted to delineate the potential mediating role of uric acid in the TT-Klotho association.

resultsMultivariable linear regression analyses revealed inverse relationships between TT and uric acid (β = - 2.75, 95% CI: - 4.21, 1.28, p < 0.001) and between uric acid and α-Klotho (β = - 4.80, 95% CI: - 6.47, - 3.13, p < 0.001). Conversely, a positive correlation existed between TT and α-Klotho (β = 5.38, 95% CI: 2.23, 8.53, p < 0.001). Updated subgroup analyses show that the association strength between α-Klotho, TT, and uric acid levels was consistent across various population settings without significant variations. Restricted cubic spline analysis identified a non-linear association between TT and uric acid with an inflection point at 201 ng/mL. Mediation analysis confirmed uric acid-mediated 18.59% of the association between TT and α-Klotho (p < 0.001), highlighting its significant intermediary role.

conclusionThis study elucidates the complex interrelationship between TT, uric acid, and α-Klotho, highlighting uric acid's significant mediating role. These findings provide novel insights into the hormonal and metabolic mechanisms underlying age-related processes and longevity.
