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
Objective: To investigate the current status of depression in women in the second and third trimesters of pregnancy, analyze the factors associated with depressive symptoms during this period,and construct an artificial neural network-based risk prediction model for depressive symptoms, with the aim of providing evidence for early screening, risk identification, and targeted intervention. Methods: A convenience sample of 588 women in the second and third trimesters of pregnancy (28 -36 weeks of pregnancy) who had regular prenatal check-ups in the obstetric outpatient clinics of two tertiary hospitals in Changsha and Hengyang from April 2023 to December 2023 was investigated using the questionnaire for depressive symptoms in the second and third trimesters of pregnancy.Spearman correlation analysis was used to explore the correlation between social support, coping style, vulnerable personality, parenting competence and the Edinburgh postpartum depression score. Binary logistic regression and a multi-layer perceptron artificial neural network were used to construct prediction models for depressive symptoms in the second and third trimesters, respectively. Results: The positive rate of depressive symptoms screening in the second and third trimesters was 42.7%.The level of social support, active coping and reactive personality were negatively correlated with depressive symptoms in the second and third trimesters of pregnancy ( Conclusion: The positive rate of depression symptom screening is higher in women during the second and third trimesters. Nursing measures can be formulated based on the associated factors in this model to support early identification and targeted intervention for depressive symptoms in the second and third trimesters of pregnancy. The prediction model for depression symptoms in the second and third trimester constructed in this study has good predictive performance and can provide a basis for clinical nurses to identify women at high risk of depressive symptoms.
