Validation of the <scp>miniPIERS</scp> model and a prognostic model for perinatal death in hypertensive pregnancy: Insights from the <scp>PREECARDIA</scp> study in Guinea‐Bissau

The miniPIERS model showed limited utility for risk prediction in this setting, where healthcare infrastructure and population characteristics differ from the model's development context. While the prognostic model for perinatal death showed better discrimination, its poor calibration and high baseline neonatal mortality in this setting suggest that the model's utility must be interpreted cautiously. Future research should focus on larger multicenter validation studies in similar low-resource settings to optimize and adapt risk prediction tools for maternal conditions such as preeclampsia.
