Prevalence of adult attention-deficit/ hyperactivity disorder symptoms among university students and their relation to sleeping duration, time management skills, and academic performance.
Article in PeerJ, 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: Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental condition that often persists from childhood into adulthood and is characterized by symptoms of inattention, hyperactivity, and impulsivity. In university students, these symptoms may negatively affect time management and academic performance. This study aimed to estimate the prevalence of adult ADHD symptoms among university students at Jazan University, Saudi Arabia, and to examine their associations with time management skills and academic performance. Methods: We conducted a cross-sectional study at Jazan University, Jazan, Saudi Arabia. We used a multistage sampling technique. We distributed 763 online questionnaires to the university students; the response rate was 87% (664 questionnaires). Of them, 612 (80.2%) questionnaires were complete and included in the analysis. We recruited male and female students from the Colleges of Medicine, Nursing, Business Administration, and Engineering. Data were collected using validated self-administered questionnaires assessing ADHD symptoms, time management skills, and academic performance. Results: Our study was conducted among Jazan University students, with a mean age of 21 years (SD = 1.6), and a predominance of male participants (64%). The prevalence of adult ADHD symptoms was 26% among Jazan University students. Significant associations were observed with female sex (odds ratio (OR) = 1.58), sleeping fewer than 4 hours per night (compared with ≥ 8 hours; OR = 2.46), and lower grade point average (GPA) (odds ratio (OR) = 2.10). Associations with the Academic Performance Scale (APS) and time management skills were inconsistent. Conclusions: Adult ADHD symptoms were more prevalent among Saudi university students than estimates reported in the global literature and were associated with female sex, insufficient sleep, and lower GPA. The inconsistent associations with academic performance measures and time management skills highlight the complexity of ADHD-related functional outcomes. These findings underscore the need for targeted interventions to support students' mental well-being and academic success.
