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

STUDY

objectivesTo examine the association between sleep duration and overweight/obesity in preschool-aged children.

methodsA total of 48,922 3-year old children enrolled in the Jiaxing Birth Cohort, who provided sleep information and anthropometric data, were included in the present study as baseline and were followed up to 5 years of age. Sleep duration was categorized as ≤ 10 hours, 11-12 hours, and ≥ 13 hours. Overweight and obesity were defined according to the cut point criteria in China. Prevalence ratios and risk ratios were used to assess the association between sleep duration and risk of overweight/obesity.

resultsIn cross-sectional analyses at baseline, the adjusted prevalence ratios (95% confidence interval) of overweight (with 11-12 h of sleep being considered the reference group) for children sleeping ≤ 10 h and ≥ 13 h were 1.13 (1.06-1.20) and 1.16 (1.09-1.24), respectively, whereas the adjusted prevalence ratios (95% confidence interval) of obesity were 1.25 (1.11-1.40) and 1.25 (1.11-1.42). In longitudinal analyses, the adjusted risk ratios (95% confidence interval) of overweight for children sleeping ≤ 10 h and ≥ 13 h were 1.48 (1.26-1.74) and 1.13 (0.96-1.34), while adjusted risk ratios (95% confidence interval) of obesity were 1.77 (1.30-2.40) and 1.19 (0.85-1.66). Restricted cubic splines regression supported U-shaped curvilinear associations between sleep duration and overweight/obesity in both cross-sectional and longitudinal analyses.

conclusionsBoth short and overlong sleep duration are associated with a higher risk of overweight/obesity in preschool-aged children. Optimizing sleep duration may be an important modifiable intervention for overweight and obesity.
