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

Objective: This study aimed to evaluate the predictive efficacy of combining serum soluble fms-like tyrosine kinase-1/placental growth factor (sFlt-1/PlGF) ratio with uterine artery Doppler ultrasound for early-onset preeclampsia (PE) before 34 weeks' gestation. Methods: A retrospective cohort analysis was conducted on 148 singleton pregnancies (control group: n = 76; early-onset PE group: n = 72) who delivered at our institution between July 2023 and June 2024. At 24-28 weeks, serum sFlt-1 and PlGF levels were quantified via electrochemiluminescence immunoassay (Roche Elecsys Results: Compared to controls, PE patients exhibited significantly elevated sFlt-1 (24.02 ± 6.68 vs 16.38 ± 7.47 μg/L; P < 0.001), reduced PlGF (1.22 ± 0.14 vs 1.54 ± 0.30 μg/L; P < 0.001), and higher sFlt-1/PlGF ratio (20.76 ± 7.71 vs 10.11 ± 4.10; P < 0.001). Doppler indices were markedly increased in PE: PI (1.34 ± 0.26 vs 0.82 ± 0.11; P < 0.001), RI (0.78 ± 0.12 vs 0.51 ± 0.07; P < 0.001), and S/D (3.89 ± 0.97 vs 2.11 ± 0.41; P < 0.001). Multivariate analysis confirmed all parameters as independent predictors (P < 0.05), with sFlt-1/PlGF ratio having the highest odds ratio (OR = 1.332, 95% CI: 1.128-1.573). The combined model achieved superior predictive performance: area under curve (AUC)=0.954 (95% CI: 0.92-0.99) vs sFlt-1/PlGF alone (AUC = 0.887; P = 0.003) or PI alone (AUC = 0.821; P < 0.001), with sensitivity 82.2%, specificity 96.7%, and accuracy 94.7%. Conclusion: Integration of sFlt-1/PlGF ratio and uterine artery Doppler parameters (particularly uterine artery PI and RI) significantly enhances early-onset PE prediction, providing a robust tool for clinical risk stratification.
