1 · What the graph read from it

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.

2 · The registry

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

Background: Postpartum depression (PPD) is a prevalent mental health condition that significantly impacts the wellbeing of mothers and their families. Early identification of high-risk women continues to be a challenge in public health practice. This study focuses on postpartum women in Chongqing, China, aiming to identify key psychosocial and demographic risk factors for PPD. Using logistic regression, we constructed and validated a predictive model for early screening, which could guide targeted preventive interventions. Methods: This cross-sectional study was conducted from January 2018 to July 2019 at four hospitals in Chongqing, China. A total of 892 valid questionnaires were collected based on predefined inclusion and exclusion criteria. Univariate and multivariable logistic regression analyses were performed to identify predictors of PPD and to construct a predictive model. The model's performance was evaluated in terms of discrimination, calibration, and clinical utility using the area under the receiver operating characteristic curve (AUC), calibration curves, and decision curve analysis (DCA), respectively. The dataset was randomly divided into a training set (70%) for model development and a validation set (30%) for internal validation. Results: Among the 892 participants, the prevalence of PPD was 10.2%. Multivariable logistic regression analysis identified four independent predictors: low delivery-related knowledge (OR = 5.47, 95% CI: 2.08-14.40), family dysfunction (moderate: 7.03, 3.79-13.02; severe: 5.14, 2.08-12.72), low social support (3.92, 1.06-14.42), and cesarean section (2.31, 1.31-4.09). The AUC of the model was 0.83 in both the training and validation sets. The calibration curve demonstrated good agreement between predicted and observed outcomes, and DCA confirmed its potential clinical utility. Conclusion: Key risk factors for PPD in this study include low delivery-related knowledge, family dysfunction, low social support, and cesarean section. The developed model performs well in the early identification of high-risk women, enabling timely interventions to improve maternal mental health.
