Associations between perceived stress and cortisol biomarkers in predominantly Latino adolescents.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The relationship between cortisol and perceived stress is poorly understood. We sought to determine whether perceived stress is associated with cortisol biomarkers in adolescents. In a sample of 229 adolescents (mean age = 15.8 years) we measured perceived stress with the 14-item Perceived Stress Scale (PSS) questionnaire, serum cortisol (sCOR), salivary Cortisol Awakening Response (CAR: 30-minute post-awakening - awakening), salivary Diurnal Cortisol Slope (DCS: evening-awakening), and total daily salivary cortisol (TDC). Multivariable linear regression was used to estimate baseline associations between PSS, TDC, and sCOR Mixed effects linear regression was used to estimate baseline associations between PSS and CAR and DCS. A twelve-week longitudinal association between PSS and cortisol biomarkers using random effects regression was tested. Analyses were adjusted for age, gender, and BMI. There were statistically significant associations between PSS and TDC (beta= -104.36 ± 34.3; p = 0.002) at baseline and between PSS and DCS at 12 weeks (beta= -0.058 ± 0.02; p = 0.01), but no association between PSS and sCOR or CAR (p > 0.26 for all) at baseline or 12-weeks. There were no associations between change in PSS and change in cortisol biomarkers longitudinally. In adolescents, perceived stress, measured by the PSS, was inconsistently associated with TDC and DCS, and consistently unassociated with CAR and sCOR. Studies reporting on PSS outcomes should exercise caution when making conclusions about cortisol biomarkers. There is a need for greater specificity of psychological stress to understand their relationship with biomarkers of stress.
