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

objectiveTo develop and internally validate a mechanistic, three-domain framework for early classification and prediction of pre-eclampsia (PE) using first-trimester angiogenic, uteroplacental, and maternal vascular biomarkers.

methodsIn a prospective cohort of 1925 singleton pregnancies screened at 11 to 13.6 weeks, placental growth factor (PGF), uterine artery pulsatility index (UtA-PI), and mean arterial pressure (MAP) were log-transformed and standardized to gestational age-adjusted multiples of the median. Prespecified percentile thresholds (PGF <10th; UtA-PI >95th; MAP >95th) defined domain abnormalities and mechanistic phenotypes. Associations with PE, fetal growth restriction (FGR), and the composite of PE or FGR were assessed using logistic regression. Discrimination (area under the [receiver operating characteristic] curve [AUC]), calibration, and clinical utility were evaluated; bootstrap internal validation was used for optimism correction; and decision-curve analysis quantified net clinical benefit.

resultsPE occurred in 104 of 1925 pregnancies (5.4%). Phenotypes were distributed as normo (81.7%), molecular (7.6%), hemodynamic (3.2%), tensional (5.1%), dual (≥2 domains; 2.1%), and triple (3/3; 0.3%). The risk of PE increased stepwise from 3.9% (normo) to 80.0% (triple) (P for trend <0.001). The three-domain model improved discrimination to an AUC of 0.81 (95% confidence interval [CI], 0.77-0.86) versus the clinical model (AUC, 0.68; P < 0.001), achieved good discrimination for isolated FGR (AUC, 0.75 [95% CI, 0.70-0.81]), and provided higher net clinical benefit among 5% to 30% thresholds. In early-onset PE (n = 14), discrimination was high (AUC, 0.99 [95% CI, 0.98-1.00]); estimates should be interpreted cautiously given the small number of events.

conclusionA first-trimester, mechanistic three-domain framework captures the pathophysiologic continuum of placental insufficiency and supports accurate, clinically meaningful early risk stratification for PE. Findings were internally validated; external validation-particularly for early-onset PE-is warranted.
