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 aimed to evaluate the predictive value of combining first-trimester pregnancy-associated plasma protein-A (PAPP-A) with second-trimester four-dimensional umbilical artery Doppler ultrasound for fetal growth restriction (FGR). Methods: This retrospective study was conducted at Lu'an People's Hospital of Anhui Province. We included pregnant women who delivered at the hospital between January 2022 and May 2024. The FGR group comprised 34 women with severe FGR, while the control group consisted of 36 women with normal fetal growth. Maternal serum PAPP-A levels were measured from first-trimester samples (11-13⁺ Results: The FGR group had significantly lower fetal weight and PAPP-A levels than those of the control group (P < 0.05). The gestational age at delivery was significantly shorter in the FGR group compared to the control group (36.19 ± 1.98 vs 38.89 ± 1.47 weeks; P < 0.05). The PI, S/D, and RI in four-dimensional color Doppler ultrasound were higher in the FGR group than those in the control group (P < 0.05). Furthermore, PAPP-A and four-dimensional color Doppler ultrasound separately showed poor predictive value for FGR, without statistically significant difference. The combined use of PAPP-A and four-dimensional ultrasound parameters demonstrated superior predictive performance, with an AUC of 0.917 (95% CI: 0.86-0.97), significantly higher than individual parameters (P < 0.05). Conclusion: The combination of first-trimester PAPP-A and second-trimester umbilical artery Doppler parameters shows high accuracy in identifying FGR, offering a clinically valuable assessment strategy.
