  1. Multiple linear regression analysis for urinary albumin excretion was performed in an incremental inclusion manner using other independent parameters at 8 weeks including body weight, blood pressure, CCr, urinary phosphate, plasma phosphate, plasma FGF23, plasma intact PTH, plasma 1,25(OH)2 vitamin D and plasma CPP. Urinary excretion of albumin and phosphate and plasma levels of FGF23, intact PTH, 1,25(OH)2 vitamin D and CPP were log-transformed prior to the analysis. Abbreviations. CCr: creatinine clearance corrected for body weight of 100 g; FGF23, fibroblast growth factor 23; CPP, calciprotein particle.
