Associations Between Stress and Hair Cortisol and Their Relationship to Alcohol Use Among Adolescents and Young Adults: An Epidemiological Cohort 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
The relationship between stress, hair cortisol and alcohol consumption has mostly been investigated among clinical and adult study samples, with inconsistent findings. The present study aimed to examine cross-sectional and longitudinal associations between chronic stress, hair cortisol and average past-year alcohol consumption within a population-based sample of adolescents and young adults. At baseline of the epidemiological cohort study, N = 1180 individuals aged 14-21 from Dresden, Germany, were assessed (11/2015-12/2016). A maximum N = 1055 were analysed in cross-sectional analyses and a maximum N = 722 in longitudinal analyses (1-year follow-up). Multivariate linear regression analyses were conducted to reveal cross-sectional associations between perceived chronic stress, hair cortisol concentration and average past-year alcohol consumption in males and females. Longitudinally, weighted linear regression models examined relationships between (a) perceived chronic stress at baseline and altered hair cortisol concentration over 1 year, (b) perceived chronic stress/hair cortisol concentration at baseline and altered average alcohol consumption over 1 year and (c) average past-year alcohol consumption at baseline and altered stress/hair cortisol concentration over 1 year. Cross-sectionally, no significant relationships were found between stress, hair cortisol and average past-year alcohol consumption at baseline. In females, higher baseline perceived chronic stress was associated with an increase in hair cortisol concentration over 1 year, whereas no relationship was found in the cross-sectional analysis between baseline perceived chronic stress and baseline past-year average alcohol consumption. When using hair cortisol as a biomarker for stress perception, the focus of future research should be on potential time lags between perceived chronic stress and hair cortisol increase.
