Observational studySleep & breathing = Schlaf & Atmung2020
Quality of sleep and quality of life measured monthly in pregnant women in South Korea.
Observational study in Sleep & breathing = Schlaf & Atmung, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeThe change in sleep patterns across the duration of pregnancy is an item of interest. The aim of this study is to provide data on pregnant women's quality of sleep (QoS) and quality of life (QoL) to determine appropriate times to screen for potential problems.
methodsThis is a multicenter, prospective, longitudinal observational study. Primigravidae, with no previous illness, completed questionnaires once a month. Strict exclusion criteria were applied in order to evaluate QoS and QoL in "normal" pregnant women.
resultsA total of 83 normal primigravidae completed this study. The mean age was 33.1 ± 4.0. During pregnancy, body mass index gradually increased, and QoS worsened to a significant degree between the fifth and ninth months (Pittsburgh Sleep Quality Index 6.8 ± 2.8 vs. 8.9 ± 3.6, p < 0.001). There was a statistically significant difference in QoL between the fifth and seventh months (Short Form-36 70.8 ± 18.3 vs. 67.3 ± 15.1, p = 0.009). There was no evidence of significant depression or suspicion of sleep-disordered breathing.
conclusionsPregnant women in South Korea have gradual worsening of QoS which becomes clinically significant by full term. QoL changes significantly between the fifth and seventh months. The results of this observational study suggest that it would be fruitful to evaluate QoS and QoL in pregnant women between the second and third trimesters.
