sKlotho (in pg/ml), albuminuria (in mg/g), and FGF-23 (in rU/ml) were ln-transferred because of skewed distribution. CVD, cardiovascular disease; CKD-MBD, CKD–mineral and bone disorders; HR, hazard ratio; 95% CI, 95% confidence interval; sKlotho, PTH, parathyroid hormone; FePi, urinary fractional phosphate excretion.
