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

purposeThis study aimed to examine if there is a difference in the prevalence of obstructive sleep apnea (OSA) and sleepiness between pregnant and non-pregnant women. It also aimed to evaluate if obstetric outcomes were associated to sleep-disordered breathing among the pregnant women.

methodsOne hundred pregnant women (gestational weeks 24-34) and 80 age- and body mass index-matched non-pregnant women underwent whole-night respiratory recordings (airflow, snoring, respiratory movements, body position, pulse oximetry). The women also answered a questionnaire including the Epworth sleepiness scale.

resultsEighty-nine percent of the pregnant women had normal body mass index (BMI). Objectively, recorded snoring was more common among the pregnant women (median 9 % of total estimated sleep time) than among the controls (4 % of total sleep time, p = 0.005). Three of the pregnant women had OSA (apnea/hypopnea index (AHI) >5), but in two cases, this was mainly due to central hypopneas. None had AHI >10. Two controls were diagnosed as OSA. Respiratory parameters including snoring showed no impact on obstetric outcomes. Total Epworth sleepiness scale (ESS) score was higher among pregnant women than among controls (median 9 vs 7, p < 0.001). There was no difference concerning the separate items. There were no significant associations between either subjectively reported or objectively recorded snoring and ESS scores.

conclusionThere was no increased prevalence of obstructive sleep apnea among pregnant women. One reason for this could be that the majority of the women in this study were non-obese. Neither OSA nor snoring was likely an explanation for the increased daytime sleepiness seen in the pregnant women.
