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

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMaternal mental health during pregnancy is a significant public health concern in rural China. Given the limited availability of professional psychological services in rural areas, understanding the factors that influence mental health and identifying simple, effective family support strategies are crucial. This study investigates the association between sleep duration and maternal mental health among pregnant women in rural northwest China.
methodsThis study was conducted among 1035 pregnant women from 10 counties in rural areas. Sleep duration was measured by self-reported, which was categorized as short (≤ 8 h), medium (8-10 h), or long (≥ 10 h). Mental health was measured using the Depression, Anxiety, and Stress Scale 21 (DASS-21). Descriptive statistics and logistic regression analyses were employed to elucidate the prevalence of sleep duration issues and explored their association with mental health. Heterogeneity analyses were performed by family support and informal social support.
results21.06% of pregnant women reported short sleep duration, 56.72% had medium sleep duration, and 22.22% had long sleep duration. In addition, 34.40%, 38.26%, and 31.88% of participants showed moderate-severe depression, anxiety, and stress, respectively. Both short and long sleep durations were significantly associated with higher risks of moderate-severe stress (short: AOR = 1.68, 95% CI: 1.14-2.49, p = 0.009; long: AOR = 1.50, 95% CI: 1.05-2.13, p = 0.024). The associations were stronger among pregnant women without husband accompany them to prenatal check-ups or with poor relationships with their mothers-in-law. Negative attitudes toward psychological counseling and lower nutrition and health knowledge scores also reinforced these effects.
conclusionsBoth short and long sleep durations were associated with higher risks of moderate-to-severe stress among pregnant women, with stronger effects observed among those lacking family or informal social support. Helping pregnant women maintain a healthy sleep duration through household involvement represents a feasible and low-cost approach, especially in rural areas where professional psychological services are limited. Strengthening family and informal social support may therefore offer practical strategies to improve pregnant women mental health.
