Perceived stress is associated with impaired artery elasticity: An observational study from the Vara- Skövde cohort.
Observational study in PloS one, 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
backgroundThis study aims to determine the association between perceived mental stress and arterial elasticity. Additionally, we will investigate potential effect modifications of sex and antihypertensive medication on this association.
methodsCross-sectional observational study based on the Vara- Skövde Cohort. After excluding individuals with missing information on perceived stress or vascular elasticity, 1015 individuals remained. Perceived stress was evaluated with the Perceived Stress Scale-10 (PSS-10). Small Artery Elasticity Index (SAEI or C2) was estimated from a Windkessel model obtained by applanation tonometry over the arteria radialis. Impaired artery elasticity was defined as the lowest sex-specific quartile of C2. The associations between perceived stress and artery elasticity indices were investigated using linear and logistic regressions with adjustments for possible confounding in different models. Due to significant interactions tests we stratified for men and women and for individuals with and without antihypertensive medication.
resultsThe mean age of study participants was 57 years and women reported significantly higher stress levels on PSS-10 than men [Women: 13.6 ± 5.6; Men: 12.4 ± 5.3; p < 0.01]. Among those 803 individuals who did not take antihypertensive medication, there was a significant association in linear regression between increase in PSS-10 and decrease in C2 (B: -0.2, 95% CI: -0.4- -0.02; p = 0.03) that was lost after adjustment for physical activity (B: -0.16, 95% CI: -0.35-0.03; p = 0.1). In logistic regression analyzes, each increment with 1-SD in PSS-10 was associated with 25% higher odds of having impaired artery elasticity in all models (OR=1.25, 95% CI: 1.01-1.55; p = 0.04).
conclusionsAmong middle-aged adults without antihypertensive medication, higher perceived stress was associated with impaired arterial elasticity.
