Central sleep apnea in pregnant women with sleep disordered breathing.
Article in Sleep & breathing = Schlaf & Atmung, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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
purposePhysiologic changes in the cardiac, respiratory, and renal systems in pregnancy likely impact ventilatory control. Though obstructive sleep apnea and snoring are common in the pregnant population, the predisposition to central respiratory events during sleep and the prevalence of such events is less well studied. The aim of this study was to assess the presence of central apneas during sleep in pregnant women and non-pregnant controls suspected of sleep disordered breathing.
methodsTwenty-five pregnant women referred for polysomnography for sleep disordered breathing were compared with non-pregnant controls matched for age, body mass index, gender, and apnea hypopnea index (AHI). Central apnea index was defined as the number of central apneas per hour of sleep, and mixed apnea index was defined as the number of mixed apneas per hour of sleep.
resultsSixty-four percent of pregnant women had a respiratory disturbance index >5 events per hour of sleep. Mean body mass index was 44.1 ± 6.9 kg/m(2) pregnant compared to 44.0 ± 7.3 kg/m(2) in controls. The total number of central apneas observed during sleep in the pregnant group consisted of two central apneas in one patient, and of 98 central apneas in 11 patients in the control group (p = 0.05). Median central apnea index was low in both groups (pregnant 0, interquartile range (IQR) 0, 0 vs. non-pregnant 0, IQR 0, 0.2, p = 0.04). Mixed apnea index was similarly low in both groups.
conclusionDespite some physiologic changes of pregnancy that impact ventilatory control, the prevalence of central sleep apnea was low in our sample of overweight pregnant women with sleep-disordered breathing.
