Serum 25-hydroxyvitamin D concentration is associated with device-estimated sleep metrics in healthy young and early middle-aged adults.

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
Study Objectives: We tested associations between serum 25-hydroxyvitamin D concentration ([25(OH)D]) and device-estimated sleep metrics, including sleep duration, sleep efficiency, sleep duration regularity, sleep timing regularity, and sleep regularity index (SRI), in young and early middle-aged adults (18-45 years). We also assessed the mediating effect of nighttime melatonin (urinary 6-sulfatoxymelatonin (aMT6s) excretion) on these associations. Methods: Participants ( Results: Serum [25(OH)D] was positively associated with sleep duration, sleep efficiency, and SRI, and negatively associated with sleep duration regularity, sleep onset timing regularity, and sleep midpoint timing regularity in model 1 (all Conclusions: Serum [25(OH)D] is independently associated with several sleep metrics in healthy adults. However, nighttime melatonin concentration did not mediate these associations, thus other mechanistic pathways must be considered.
