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: This study aims to develop a model to predict preterm birth in patients with velamentous cord insertion (VCI) during the second trimester. Methods: This retrospective cohort study enrolled 240 singleton pregnancies (135 VCI cases and 105 controls) from January 2023 to December 2024. Four prediction models were constructed using univariate analysis and LASSO regression: Model 1 (midtrimester clinical parameters), Model 2 (late-pregnancy ultrasound parameters), Model 3 (combined mid- and late-pregnancy parameters), and Model 4 (midtrimester growth deviation indices, including BPD Results: The preterm birth rate was significantly higher in the VCI group than in the control group (17.8% vs. 5.7%, Conclusion: The midtrimester ultrasound deviation model enables early identification of high-risk VCI pregnancies, facilitating individualized delivery timing decisions while minimizing unnecessary interventions.
