Association between aging phenotypes and chronic kidney disease: evidence from the NHANES and Mendelian randomization.

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
purposeBiological aging was found to be associated with the higher prevalence of several diseases, but it is unclear in the prevalence of chronic kidney disease (CKD). This study investigated the effect of aging phenotypes, characterized by PhenoAge (PA), Klemera-Doubal Method (KDM), allostatic load (AL), homeostatic dysregulation (HD), and telomere length (TL) on CKD from the perspective of both clinical relevance and genetic susceptibility.
methodFrom the clinical perspective, the study analyzed data from 7482 participants in the National Health and Nutrition Examination Survey 2006-2015. Logistic regression and restricted cubic spline (RCS) models were employed to evaluate both linear and nonlinear associations between aging phenotypes and the prevalence of CKD. From the genetic susceptibility perspective, Mendelian randomization analyses were conducted to establish causality between telomere length and CKD outcomes.
resultMultivariate logistic regression revealed that PA, KDM, AL, and HD were associated with an increased prevalence of CKD, with PA remaining a significant risk factor after adjusting for covariates (OR = 1.0714, 95% CI = 1.0558-1.0872). RCS curves further indicated a nonlinear relationship between PA, AL, HD, and CKD prevalence (P < 0.001). Besides, inflammation indicators were found to mediate this association. Mendelian randomization analysis demonstrated a significant causal relationship between telomere length and CKD risk across multiple datasets. The results were as follows: Discovery Group (OR = 0.892, 95% CI = 0.832-0.956, P = 0.001) and (OR = 0.896, 95% CI = 0.836-0.961, P = 0.002); Replication Group (OR = 0.872, 95% CI = 0.808-0.940, P < 0.001) and (OR = 0.909, 95% CI = 0.854-0.967, P = 0.003).
conclusionThese findings underscore the strong connection between aging phenotypes and CKD risk, with the mediated effect of inflammatory markers, contributing to the early disease prevention and therapeutic strategy development.
