Sleep duration and chronotype of pregnant women in the United States: An online cross-sectional survey study.
Article in Preventive medicine reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06413784 (Examining The Effect of Chronotype Differences on Sleep Quality and Pregnancy Symptoms in Pregnant Women), which is not on this map. Not yet cited in PubMed.
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.

Abstract
Sleep is an important behavior, and during pregnancy plays a critical role in promoting the health of both woman and child. Therefore, identifying and addressing sleep parameters during pregnancy, and associated disparities in maternal-child health outcomes, is a public health priority. This studied aimed to examine chronotype and sleep duration in pregnant women by sociodemographic factors. An online survey was distributed to currently pregnant women living in the greater Washington, DC, area of the United States from March to May of 2022. The survey included the ultra-short version of the Munich Chronotype Questionnaire (µMCTQ), which was used to calculate the mid-point of sleep time (MST; a measure of chronotype) and sleep duration, as well as demographic questions. Linear regression was used to assess differences in sleep outcomes by demographic factors. A sample of n = 142 currently pregnant women were eligible for analysis. In covariate adjusted models, sleep duration was longer among respondents ages 25-34 (09:52) compared with younger respondents ages 18-24 (08:59; p = 0.014), and shorter for those with a household income ≥ 100,000 United States dollars (USD) (07:42) compared with those with a household income < 50,000 USD (08:59; p = 0.001). No differences in mean mid-point of sleep were identified across demographic factors. Differences in sleep duration by age and household income were found among currently pregnant women. Future studies should investigate sleep parameters and other factors that may influence maternal-child health disparities.
