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 Sleep deprivation is a growing concern among students, particularly in demanding fields such as health sciences, where it can impair cognitive function and academic performance. This study aimed to investigate the prevalence of sleep deprivation and its impact on health sciences students at Umm Al-Qura University. Methods A cross-sectional study was conducted during the 2024-2025 academic year, involving 211 undergraduate health sciences students. Data were collected through an online questionnaire assessing sociodemographic characteristics, sleep patterns, academic performance, stress levels, and electronic device use. Statistical analyses included independent t-tests, chi-square tests, and regression analyses to evaluate associations between sleep quality and academic outcomes. Results Among the participants, 102 (48.3%) reported difficulty sleeping. Poor sleep quality was significantly associated with shorter sleep duration, longer sleep latency, and irregular sleep schedules. Students with sleep difficulties were more likely to use digital devices before bedtime (72 (70.6%) vs. 56 (51.4%); p = 0.007) and to feel less refreshed upon waking (p = 0.001). Poor sleep quality scores were also significantly associated with poorer academic performance (p = 0.018), higher stress levels (p = 0.022), and difficulty completing academic tasks on time (p = 0.0039). Notably, 82 participants (38.86%) lacked awareness of recommended sleep duration. Conclusion This study highlights the high prevalence of sleep deprivation among health sciences students. Although sleep difficulties were commonly reported, the findings showed mixed associations with academic performance. Interventions focusing on reducing screen time, managing stress, and improving sleep education are recommended to enhance sleep quality. Addressing sleep deprivation is essential for improving student well-being and supporting academic success.
