Daily behavioral profiles and academic underperformance among university students: a cross-sectional study.
Article in Frontiers in psychology, 2026. 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
Background: Daily routines may be associated with university students' academic outcomes, but isolated-exposure analyses can obscure how behaviors co-occur. We examined associations between learning and lifestyle behaviors and academic underperformance and explored multivariable behavioral profiles. Methods: This cross-sectional study included 322 first- to third-year life-sciences undergraduates. The primary outcome was academic underperformance, defined as grade point average (GPA) < 2.00. Exposure-specific and primary multivariable associations were estimated using Firth penalized logistic regression. Breakfast frequency and breakfast timing were modeled separately because of structural overlap. Mixed ordinal and categorical behaviors were clustered using Gower dissimilarity and partitioning around medoids (PAM); Results: Academic underperformance occurred in 97 students (30.12%). In the primary frequency model, compared with eating breakfast every day, eating breakfast sometimes (adjusted odds ratio [aOR] = 7.37, 95% confidence interval [CI]: 1.65-70.32) and never eating breakfast (aOR = 30.89, 95% CI: 6.00-317.35) were associated with higher odds of underperformance. Gaming for 4-6 h/day (aOR = 5.58, 95% CI: 2.36-14.19) or >6 h/day (aOR = 13.70, 95% CI: 3.46-60.29), compared with <2 h/day, showed similar associations. Formal interaction tests by sex and academic year were not significant. PAM identified a Dysregulated Routine profile ( Conclusion: Lower breakfast frequency and prolonged gaming remained associated with academic underperformance, and the two routine profiles differed markedly in academic outcomes. These exploratory, cross-sectional findings require replication in prospective cohorts before they can be translated into student-support strategies.
