Sleep quality measured by cardiopulmonary coupling spectrogram in pregnant women predicts neonatal outcomes.

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
STUDY
objectivesWe assessed the impact of objective sleep quality during pregnancy, estimated using cardiopulmonary coupling sleep spectrograms, on neonatal outcomes.
methodsWe conducted a secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b). Cardiopulmonary coupling analysis was done using the raw photoplethysmogram signal within the oximetry sensor (photoplethysmogram) from a home apnea sleep test. High- and low-frequency coupling reflect stable and unstable sleep, respectively. A multicomponent Sleep Quality Index integrates sleep stability and fragmentation. Regression analysis was done to identify the relationship between cardiopulmonary coupling metrics and neonatal outcomes.
resultsOximetry/photoplethysmogram data from the early and middle term of pregnancy (3,003 and 2,168 participants in early-term and middle-term pregnancy, respectively) were available. A high Sleep Quality Index score in early-term pregnancy decreased the risk of small gestational age (odds ratio [OR] 0.297, 95% confidence interval [CI] 0.147-0.603,
conclusionsSleep quality measured by cardiopulmonary coupling spectrograms was associated with neonatal outcomes. Sleep quality may be a target for clinical care during pregnancy.
