The mediating role of pregnancy-related anxiety in the relationship between maternal family function and prenatal depression: the moderating effect of sleep latency in late pregnancy.

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
objectiveThe current study aims to explore the relationship between Family function and depression, examining the mediation and moderation effects of pregnancy-related anxiety (PRA) and sleep latency, respectively.
methodA cross-sectional survey was conducted among pregnant women in the Ningxia Hui Autonomous Region between February 2022 and December 2024, obtaining 7622 valid questionnaires. Model 4 and Model 7 in PROCESS were used to analyse the mediating effect of pregnancy-related anxiety and the moderating effect of sleep latency. A bootstrap method was conducted to test the mediating and moderating effects.
resultsAfter adjusting for covariates, the mediating effect of PRA explained 18.68% (95% CI: -0.094, -0.06) of the association between Family function and prenatal depression (EPD). The results indicate that the interaction term (Family function * sleep latency) has a negative effect on PRA (β = -0.096, 95% CI: -0.160, -0.032). This implies that the protective effect of good Family function in reducing PRA is weakened as sleep latency increases. Further analysis by different pregnancy periods revealed that this regulatory effect was only statistically significant in the third trimester (β = -0.127, 95% CI: -0.226, -0.028).
conclusionThis paper proved that the Family function negatively predicted depression, and PRA served as a mediator between Family function and depression during pregnancy. Besides, the protective role of sleep quality on individuals’ mental health was identified. CLINICAL TRIAL NUMBER: Not applicable.
