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
Background Early identification of preeclampsia remains challenging, particularly in resource-limited settings. Although several clinical, biochemical, and Doppler markers have been explored, their individual predictive performance remains limited, necessitating evaluation of combined approaches. Objectives This study assesses the predictive value of mean arterial pressure (MAP), uterine artery Doppler pulsatility index (PI), pregnancy-associated plasma protein-A (PAPP-A), and mean platelet volume (MPV), individually and in combination, for early prediction of preeclampsia. Materials and methods In this prospective study, 150 singleton pregnancies were evaluated between 11 and 14 weeks of gestation. MAP, uterine artery Doppler PI, serum PAPP-A, and MPV were measured at recruitment. Participants were followed until delivery. Univariate analysis, logistic regression, receiver operating characteristic analysis, and detection rate assessment were performed. The study was approved by the Institutional Ethics Committee and conducted in accordance with the Declaration of Helsinki. Results Preeclampsia was observed in 19 women (12.7%). Among the individual markers, the highest discriminative ability was observed for MAP (AUC 0.84), and the MPV was the only predictor to show significance on multivariate analysis. PAPP-A and uterine artery Doppler PI were significantly different between the normotensive and preeclampsia groups in univariate analysis but did not demonstrate high predictive ability. The four-parameter model incorporating MAP, MPV, PAPP-A, and uterine artery Doppler PI demonstrated the highest predictive ability for preeclampsia (AUC 0.87; sensitivity 83.3%, specificity 81.5%). Conclusion The combination of MAP, MPV, PAPP-A, and uterine artery Doppler PI demonstrated higher predictive performance than individual markers in this study population and may support first-trimester risk stratification for preeclampsia.
