This study externally validates a machine-learning model (MLM) for predicting preterm preeclampsia (PE) using sFlt-1/PlGF ratio, NT-proBNP, and uric acid. The MLM showed significantly better positive predictive value (PPV) and specificity than the sFlt-1/PlGF ratio alone, with slightly improved sensitivity and negative predictive value (NPV). The model's performance improved as the delivery date approached, particularly for early-preterm PE.
