The association between sleep trajectories throughout pregnancy and postpartum pain in individuals with overweight or obesity: A prospective cohort study.
Article in Journal of psychosomatic research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundPain after childbirth impacts maternal and infant outcomes. While sleep affects pain in adult populations, research during the perinatal period is limited. This study examines the association between sleep quality and duration before delivery and throughout pregnancy with pain during postpartum hospitalization.
methodsThis analysis included 118 pregnant individuals with a pre-pregnancy BMI ≥ 25 kg/m
resultsTwo trajectories for sleep quality and two for sleep duration were identified. The "Consistently poor" group showed increasing PSQI scores from 9 to 11, while the "Late worsening" group's scores increased from 4 to 6. The "Late decreasing" duration group consistently slept 6-7 h, while the "Consistently short" group maintained 5-6 h nightly. No statistically significant associations were found between sleep quality (expβ = 0.70, 95% CI: 0.45 to 1.10) or sleep duration trajectories (expβ = 0.68, 95% CI: 0.41 to 1.13) throughout pregnancy and cumulative pain burden.
conclusionsSleep quality and duration changes during pregnancy were not associated with postpartum pain in this cohort. Future research should explore sleep's impact on pain later in the postpartum period when chronic pain may develop.
