Covariate As reported
Age 38.5 (IQR 31.5–43.3) yr
Weight 69.5 (IQR 60.7–78.2) kg
BMI 23.3 (IQR 21.4–26.5) kg/m²
CrCl 117 ± 34 mL/min
SCr 0.866 ± 0.192 mg/dL

Q = 20.2 \cdot \left(\frac{Weight}{69.45}\right)^{2.38}

Implementation notes

Two-compartment model developed in healthy Korean volunteers with normal renal function. Residual widened from the paper's tight 6.94% for stable real-world fitting.
