GFR estimating equations to predict GFR from serum cystatin C. Refit coefficients from entire dataset

Equation 1: eGFR = 76.7*CysC−1.19
Equation 2: eGFR = 127.7* CysC−1.17 * age−0.13 * (0.91 if female) * (1.06 if black)
Equation 3: eGFR = 177.6* SCr−0.65 * CysC−0.57 * age−0.20 * (0.82 if female) * (1.11 if black)
