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
objectiveThis study aims to enhance antenatal detection of placenta accreta spectrum (PAS) and predict severe hemorrhage at delivery using machine learning by evaluating the association between antenatal hematologic index trends across trimesters, imaging markers, and patient history.
methodsWe retrospectively analyzed 2017-2023 data from a PAS referral center, including demographics, laboratory results, ultrasounds, and outcomes. Patients with confirmed PAS (cases) were compared to those with antenatal risk but no histopathologic evidence of PAS (controls). Statistical analyses and machine learning models were developed to predict PAS. We also used machine learning to predict severe hemorrhage (>1500 mL) in the cases.
resultsA total of 186 PAS cases and 217 controls were identified, showing significant differences in body mass index, gravidity, parity, prior cesarean deliveries, gestational age at delivery, and PAS ultrasound findings. Logistic regression highlighted prior cesarean deliveries (odds ratio [OR] 1.8; 95% confidence interval [CI] 1.3-2.4) and second (OR 28.1; 95% CI 12.7-60.8) or third trimester ultrasound markers (OR 27.6; 95% CI 13.2-61.1) as strong predictors of PAS. Third trimester mean platelet volume was inversely associated with PAS (OR 0.55; 95% CI 0.39-0.78). Machine learning models achieved high accuracy. Model 1 predicted PAS with 90% accuracy. Model 2 predicted PAS with 88.8% accuracy using early gestational hematologic markers. Model 3 predicted severe hemorrhage (>1500 mL) with 74.3% accuracy.
conclusionMachine learning models combining patient history, imaging, and hematologic markers detect PAS and predict hemorrhage with up to 90% accuracy. These tools improve antenatal diagnosis of PAS, which enhances maternal outcomes by enabling early identification and better resource allocation.
