Association between ramadan fasting, sleep disturbances, fatigue, and academic performance among Iraqi university students: A cross-sectional study.

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
backgroundRamadan fasting intersects with university students' academic and health behaviors, but its effects on sleep, fatigue, and academic performance remain contested. This study examines these relationships in Iraqi medical students, a population experiencing both academic rigor and cultural observance.
methodsA cross-sectional web-based survey was conducted among 922 Iraqi medical students from March 26 to April 9, 2024. Validated Arabic versions of the Epworth Sleepiness Scale (ESS-AR; range: 0-24) and the Fatigue Questionnaire (FQ-AR; total score: 0-11, with subscales for physical [0-7] and mental fatigue [0-4]) were administered. ESS-AR scores were interpreted as follows: 0-5 = low sleepiness, 6-10 = normal, 11-12 = mild, 13-15 = moderate, and 16-24 = severe. An FQ-AR total score > 4 indicated severe fatigue. Academic performance was assessed using a pre-tested, culturally adapted questionnaire.
resultsMost students (90.1%) reported fasting-related sleep disruptions. Low academic performance was observed in 61.4% of students, and it was associated with higher levels of physical fatigue (adjusted odds ratio [aOR] = 0.72, p < 0.01) and mental fatigue (aOR = 0.60, p < 0.01). Counterintuitively, stress (aOR = 1.68, p < 0.01) and sleep disturbances (aOR = 2.54, p < 0.01) were linked to better performance. This may reflect reverse causality: high-achieving students maintain rigorous study habits during Ramadan, inadvertently increasing their stress and sleep disruptions.
conclusionsOur findings demonstrate that Ramadan fasting significantly impacts students' sleep patterns and fatigue levels, with nuanced effects on academic performance. While fatigue negatively correlated with outcomes, the counterintuitive stress-performance association suggests high-achievers may maintain performance despite challenges. Future research should explore targeted interventions to support student wellbeing during religious observances, while institutions should adapt policies to accommodate the unique challenges faced by fasting students.
