a ΔP, transglomerular hydrostatic pressure difference; Kf, ultrafiltration coefficient; r0 and ω0, predicted values using isoporous+shunt model for pore radius and shunt contribution, respectively; U and S, predicted values using log-normal model for mean pore radius and standard deviation of pore radius, respectively.
