Prevalence of poor sleep quality before cesarean delivery and its association with postpartum quality of recovery and postpartum depressive symptoms: a prospective observational study.
Observational study in Journal of anesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 primary objective of this study was to estimate the prevalence of sleep quality among patients hospitalized for cesarean delivery, with a secondary objective of assessing the impact of sleep quality on postpartum outcomes.
methodsThis prospective observational study included patients aged ≥18 years scheduled for elective cesarean delivery under spinal anesthesia admitted a day before delivery. The incidence of poor sleep quality (Richards-Campbell Sleep Questionnaire score <50) was estimated. Mean differences in obstetric quality-of-recovery-11 (ObsQoR-11) scores on postpartum days 1, 3, and 5 and the Edinburgh Postnatal Depression Scale (EPDS) score at 1 month after childbirth between those with and without poor sleep quality were evaluated using effect sizes. Multiple linear regression adjusted for relevant factors, including the Pittsburgh Sleep Quality Index, was used to evaluate the impact of poor sleep quality on the ObsQoR-11 score on only postpartum day 1.
resultsOf 93 included patients, 48.3% (38.4-58.4%) met the criteria for poor sleep quality. The effect sizes for poor preoperative sleep quality and the ObsQoR-11 and EPDS scores ranged from 0.28 to 0.55. Multiple regression analyses revealed an association of preoperative poor sleep quality with the ObsQor-11 score on postoperative day 1 [Adjusted beta (95% confidence interval): - 18.8 [(- 36.5, - 1.2)].
conclusionThe prevalence of preoperative poor sleep quality in hospitalized pregnant women scheduled for elective cesarean delivery was 48%, which was significantly associated with quality of recovery on postpartum day 5 and EPDS scores at 1 month post-childbirth.
