1/creatinine values before and after EPO treatment. The rate of progression of renal function decline as reflected by the linear regression lines slowed from -0.0140 dL/mg·month ± 0.0119 (mean ± SD) to -0.0017 dL/mg·month ± 0.0090 (non-parametric Wilcoxon matched pairs signed rank sum test: Z statistical value of -2.91 which corresponds to a two tailed P = 0.004) after starting EPO at Month 0.
