1 · What the graph read from it

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.

2 · The registry

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

objectiveTo compare the effects of obesity on sleep quality, the anthropometric and autonomic parameters of adolescents. MATERIAL AND

methodsA cross-sectional study was carried out with adolescents aged 11 to 18, analyzing parameters such as BMI, sleep quality records, waist circumference, fat percentage, blood pressure and sexual maturation, in addition to autonomic cardiac function through the analysis of heart rate variability.

resultsThe anthropometric parameters of waist circumference, percentage fat mass, were significantly higher in the group of obese adolescents. Sympathetic modulation in LF% was significantly higher in obesity. Parasympathetic modulation in HF% was significantly lower in obese than in eutrophic.

conclusionObese adolescents do not have poor sleep quality; there is no distinction between boys and girls regarding the analyzed variables; however, obesity alone was responsible for negatively influencing anthropometric parameters, as well as impairing the autonomic cardiac modulation.
