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
backgroundSleep disturbance and psychosocial stress are emerging contributors to hypertensive disorders of pregnancy. The present cohort was recruited during the COVID-19 period, a time marked by substantial changes in prenatal care delivery, social support, and daily routines, which may have influenced maternal sleep and stress burden.
objectiveThis study aimed to evaluate the independent and integrated associations between maternal sleep quality, psychological stress, and pregnancy outcomes in women at moderate to high risk for preeclampsia.
methodsIn a single-center observational cohort of 170 pregnant women enrolled at 16 weeks' gestation, sleep was assessed using the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Fitbit Sense 2™ wearable data, while stress was measured through the Perceived Stress Scale (PSS-10), Generalized Anxiety Disorder-7 (GAD-7), and morning salivary cortisol. Associations with preeclampsia, birth weight, gestational age, and NICU admission were analyzed using multivariate regression and receiver operating characteristic (ROC) models. The COVID-19 period was treated as the contextual background of recruitment rather than as a directly compared exposure.
resultsPoorer subjective sleep quality (higher PSQI) correlated negatively with birth weight (r = -0.34,
conclusionsIn high-risk pregnancies, integrated evaluation of sleep and stress parameters may improve the prediction of fetal growth impairment and preeclampsia beyond single-domain models. These findings support the incorporation of psychosocial and behavioral markers into antenatal risk stratification. Because no pre-pandemic or post-pandemic comparator group was included, the COVID-19 period should be interpreted as the contextual background of the study rather than as an independently tested exposure.
