Clinical risk assessment tool using PAI score and Neutrophil-to-Lymphocyte ratio
Enter Clinical Parameters
Input the patient's PAI score and N/L ratio to calculate the prediction
Placental Accreta Index score
Neutrophil-to-Lymphocyte ratio
Formula Reference
Score = -1.999 + (0.518 × PAI) + (0.182 × N/L)
Positive: Score ≥ 1.035 indicates predicted risk
Negative: Score < 1.035 indicates no predicted risk
