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

aimsTo examine the association of sleep impairment with gestational diabetes mellitus (GDM) and its subtypes.

methods29,183 pregnant women from the Born in Guangzhou Cohort Study were included. Information on sleep quality, sleep duration and sleep-disordered breathing (SDB) symptoms were collected. GDM was diagnosed using a 75 g, 2h oral glucose tolerance test and medical records. GDM was categorised into three subtypes. Poisson regression models were performed.

resultsIn total, 4713 (16.2%) were diagnosed with GDM. Poor sleep quality, short nighttime sleep duration and SDB symptoms were associated with increased risks of GDM, with adjusted RR of 1.07 (95% CI 1.01, 1.13), 1.12 (95% CI 1.04, 1.22) and 1.19 (95% CI 1.10, 1.30), respectively. Short nighttime sleep duration and SDB symptoms were also associated with higher risks of the subtype of combined impaired fasting glucose and impaired glucose tolerance (IFG + IGT) (RR 1.55, 95% CI 1.22, 1.96; RR 1.80, 95% CI 1.42, 2.29, respectively). Long nighttime sleep duration was associated with lower risks of the subtype of isolated impaired glucose tolerance (i-IGT) (RR 0.89, 95% CI 0.80, 0.99).

conclusionsOur findings indicate that pregnant women with sleep impairment are more likely to develop GDM, especially the IFG + IGT subtype. Reducing sleep impairment, particularly SDB symptoms, may be a target for intervention to prevent GDM.
