Screen Time and Objectively Measured Sleep of U.S. College Students: A Brief Report.
Article in International journal of exercise science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 objective was to investigate screen time (ST) and objectively measured sleep quality in college students. Participants were undergraduate students attending a large metropolitan public university in the southeastern U.S. Participants wore accelerometers on their wrist for 24hr/day for 14 days to capture sleep outcomes, and completed a survey reporting ST duration. Analyses explored weight-status, race/ethnicity, and sleep patterns (presence of daytime sleep) differences among students. Participants (n=29, 86% female, ~21.5 years old, 38% White, 35% Overweight/Obese) slept for an average of 433.8 minutes/night, reported 419.1 minutes of daily ST, and 112 minutes of ST after 10:00PM. College students with daytime sleep (i.e., napping) reported approximately -92 minutes less of daily ST than peers (p=0.04; effect size=0.86). Further studies in larger, diverse samples are needed to explore ST and sleep, specifically the causal relationship and its potential to impact the health of college students at greatest risk of poor health outcomes.
