  1. aeGFR(ml/min/1.73m2) calculated for adult females at various ages within the childbearing age range, using the CKD-EPI formula [45] without ethnicity coefficients
  2. beGFR < 45 ml/min/1.73m2 indicates Stage 3b CKD. Therefore, all women with pre-pregnancy serum creatinine ≥150micromol/L will have CKD Stage 3b or higher
