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
backgroundSleep quality has an important role in brain functioning and development. Affected sleep quality and mental health can negatively affect the academic performance of college students.
objectiveTo assess the effect of sleep quality and mental health on the academic performance of medical students at King Abdulaziz University, Jeddah, Saudi Arabia.
methodsWe conducted a cross-sectional study among medical students at King Abdulaziz University. The dependent variable was the current grade point average (GPA). For the independent variables, two validated tools were used in the study: the Pittsburgh Sleep Quality Index (PSQI) for sleep assessment; and the Depression, Anxiety and Stress Scale (DASS-21) for mental health assessment.
resultsA total of 382 responses were analyzed. The majority of students (86.6%) had GPAs greater than 3.75/5, while only 1% of the sample had a GPA lower than 2.75/5. The PSQI showed a median and interquartile range of (9, 6-11). Normal DASS-21 represented the majority as follows: depression at 67%, anxiety at 63.1%, and stress at 82.2%. In the statistical analyses, sleep quality, depression, anxiety, and stress were not statistically significant with the student's GPA.
conclusionLow levels of sleep quality were found among medical students in our study. While sleep quality and mental health status did not show an effect on the GPA of the medical students, lower sleep quality was significantly correlated with increased scores of depression, anxiety, and stress. Our findings mandate interventions directed at improving sleep quality among medical students.
