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

Our objective was to evaluate the associations between habitual daytime napping and diabetes and whether it varies by sex, menopause, and sleep quality. We conducted a population-based cross-sectional study in 8621 eligible individuals aged 40 years or older. Information on daytime napping hours, night-time sleep duration, history of menstruation, and sleep quality was self-reported. Diabetes was diagnosed according to the 1999 World Health Organization diagnostic criteria. The prevalence of diabetes was 19.4 % in men and 15.6 % in women. Increased daytime napping hours were positively associated with parameters of glycometabolism in women, such as fasting plasma glucose, oral glucose tolerance test (OGTT) 2-h plasma glucose, and Hemoglobin A1c (HbA1c, all P for trend <0.05). In women, the prevalence of diabetes in no-habitual daytime napping group, 0-1-h daytime napping group, and more than 1-h daytime napping group were 14.5, 15.6, and 20.8 %, respectively (P for trend = 0.0004). A similar trend was detected in postmenopausal women (P for trend = 0.002). In multivariate logistic regression analysis, compared with no-habitual daytime napping postmenopausal women, those with daytime napping more than 1 h had higher prevalent diabetes (odds ratios 1.36, 95 % confidence interval, 1.04-1.77). In subgroup analysis of postmenopausal women, associations of daytime napping levels and prevalent diabetes were detected in older, overweight participants with good sleep quality who have not retired from work. In conclusion, our study suggests that habitual daytime napping is associated with prevalence of diabetes in postmenopausal women.
