Chronotype and Sleep Timing by Race-Gender: The CARDIA Sleep Study.
Article in Journal of biological rhythms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Chronotype indicates a person's "circadian preference," that is, the time of day when they prefer to perform certain activities (e.g. a "morning" vs "evening" person). Sleep timing is related to chronotype but is also constrained by social requirements. When sleep timing does not align with chronotype, circadian disruption can occur, and circadian disruption impairs cardiometabolic health. There are well-known racial disparities in cardiometabolic health whereby Black adults are at higher risk. It is not well-known, however, whether sleep timing within each chronotype varies between Black and White adults, which was the focus of these analyses. These data are from a cross-sectional sleep study conducted in 2020 to 2023 as an ancillary to the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, in the United States. The Morningness-Eveningness Questionnaire (MEQ) captured chronotype in 2,373 participants aged 52-70 years. Chronotype was based on both overall MEQ score and question 19 categories. A subset of participants wore a wrist actigraphy monitor for ~7 days to assess sleep timing (
