Sex- and age-specific associations between metabolic phenotypes and brachial-ankle pulse wave velocity in adults: a cross-sectional study.

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
Objective: To examine age- and sex-stratified associations between metabolic phenotypes and brachial-ankle pulse wave velocity (baPWV) in adults undergoing routine health examinations. Methods: This cross-sectional study included 9,981 Chinese adults classified as metabolically healthy normal weight (MHNW), metabolically healthy obesity (MHO), metabolically obese normal weight (MONW), or metabolically unhealthy obesity (MUO) according to body mass index, homeostasis model assessment of insulin resistance, and metabolic syndrome status. Elevated baPWV was defined as mean bilateral baPWV >1700cm/s. Logistic regression analyses were stratified by sex and age (<50 and ≥50 years) and adjusted for age, smoking, and alcohol consumption. False discovery rate correction, phenotype-by-sex interaction testing, Firth logistic regression, and continuous-baPWV sensitivity analyses were performed. Results: Elevated baPWV was present in 7.5% of participants. Compared with MHNW, MONW (adjusted OR range, 2.58-7.68) and MUO (adjusted OR range, 2.34-6.60) were associated with higher odds of elevated baPWV in all four sex-age strata, with associations remaining significant after false discovery rate correction. MHO was not significantly associated with elevated baPWV. The adjusted phenotype-by-sex interaction was not significant ( Conclusion: MONW and MUO, but not MHO, were consistently associated with less favorable baPWV profiles across sex and age strata. Assessing metabolic health alongside body mass index may provide additional information for vascular risk characterization. Longitudinal multicenter studies are needed to confirm temporal and clinical significance.
