Renal function estimates with different methods: CG and MDRD4. Divide by 88.4 to get creatinine concentration in mg/ml. Mean±SD, p<0.05 is regarded as significant.
*N=322.
†N=268.
BMI, body mass index; BSA, body surface area; CG, Cockcroft and Gault; MDRD4, modification of diet in renal disease equation 4
