Biological Age as a Predictor of Arterial Stiffness in Young and Early Midlife Black and White Women.
Article in American journal of hypertension, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChronological age (CA) is independently associated with arterial stiffness, but it is not a sufficient measure of aging or the disparities related to disease risk. While biological age (BA) is considered a more accurate indicator of disease risk, the relationships among BA, CA, and arterial stiffness remain inconclusive.
methodsIn 222 women (n = 143 White, n = 79 Black) enrolled in the Predictive Health Institute cohort (age range 25-49), arterial stiffness was assessed using carotid-femoral pulse wave velocity (cfPWV), measured by applanation tonometry (SphygmoCor). BA was estimated using the Klemera-Doubal method from 11 different clinical biomarkers and CA. Accelerated age (AccA) was calculated as the difference between BA and CA. Overall and race-specific associations between BA and arterial stiffness adjusting for sociodemographics, health behaviors, and clinical factors were estimated using multiple linear regression.
resultsMean (SD) CA was 41.4 (6.3) years in Black women and 39.8 (6.0) years in White women, respectively. Mean (SD) BA, AccA, and cfPWV were 43 (13.1) and 1.6 (12.9) years, and 7.3 (1.1) m/s in Black women and 36 (10.8) and -3.2 (10.6) years, and 6.3 (0.8) m/s in White women (Black-White difference in BA: 6.4 years, P = <0.001). Higher BA was associated with a 0.015 m/s per year (95% CI: 0.002, 0.029, P = 0.028) higher cfPWV after adjustment for demographic and CVD risk factors, without evidence of an interaction by race (P = 0.65).
conclusionsBA was associated with arterial stiffness in the fully adjusted model. Targeting modifiable risk factors may promote healthy vascular aging and reduce subclinical CVD progression.
