Timing of Physical Activity and Associations with BMI and Weekly Physical Activity in Young Adults: A Cross-Sectional Analysis.
Article in Research quarterly for exercise and sport, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 timing of physical activity has been associated with weight and moderate-to-vigorous physical activity (MVPA) in adults. However, few studies have tested associations in young adults, who are biologically and behaviorally different from adults. Young adults (18-35 yr) enrolled in a weight management program provided body mass index (BMI) and 4-7days of ActiGraph accelerometer wear time at baseline. Activity time of day was divided into the following quartiles: morning (06:00-11:59), afternoon (12:00-15:59), evening (16:00-18:59), and night (19:00-00:59). The proportion of weekly MVPA minutes occurring in each time category was used to predict BMI and total weekly MVPA using linear regression models. Marginal trends were estimated for the full sample and by sex. The analytic sample (
