| Variables | BUN (mmol/L) | P‐trend | Per log‐SD increment | |||
|---|---|---|---|---|---|---|
| Q1 (<2.40) | Q2 (2.40‐2.91) | Q3 (2.91‐3.50) | Q4 (≥3.50) | |||
| Excluding participants with low eGFR (<90 mL/min per 1.73 m2) | ||||||
| Cases (%) | 583 (18.33) | 653 (18.87) | 724 (22.75) | 927 (26.96) | ||
| Age‐adjusted | 1.00 (Ref.) | 1.02 (0.90‐1.15) | 1.28 (1.13‐1.45) | 1.62 (1.44‐1.82) | <.001 | 1.11 (1.07‐1.16) |
| Multivariable‐adjusted | 1.00 (Ref.) | 0.99 (0.87‐1.13) | 1.21 (1.06‐1.37) | 1.49 (1.32‐1.68) | <.001 | 1.08 (1.04‐1.13) |
Multivariable‐adjusted models were adjusted for maternal age, education, gravidity, parity, baseline BMI, gestational weight gain, systolic BP, FPG, WBC, haemoglobin and eGFR.
