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
Introduction: Changes in sleep patterns increase susceptibility to weight gain. Objective: To estimate the association between the quality and quantity of sleep hours per night and Body Mass Index (BMI) in Mexican college adolescents. Materials and methods: Cross-sectional study conducted among incoming nursing students in a public university in Mexico. Convenience sampling was used, involving n=134 students (18-19 years old), volunteers, and enrolled in the nursing program. Sleep quality and quantity were measured through the Pittsburgh Sleep Quality Index (PSQI). BMI was calculated using the standard formula. The protocol was approved by the School of Nursing Ethics Committee, and the participants signed informed consent. Results: Mean age 18.21 years (SD= .42 years), 82.84% female, 45.52% overweight or obese (95% CI= 35.46 -52.86%). 44.02% of participants reported sleeping < 6 hours per night, and 50.00% reported poor sleep quality in the past four weeks. After adjustment for age, sex, and occupation, sleep quality was not associated with BMI (OR= 1.01; 95% CI= .94 -1.08; z= .31; p= .75); increased BMI was associated with a greater likelihood of sleeping 6 hours or less (OR= 1.08; 95% CI= 1.01 - 1.16; z= 2.25; p= .02). Discussion: Hormonal changes, behavioral factors, and the environment may explain the association. Conclusions: It is advisable to implement educational strategies to improve sleep hygiene among this population.
