Figure 2From: Characteristics of urinary and serum soluble Klotho protein in patients with different degrees of chronic kidney disease Not only the urinary excreted Klotho but also the serum Klotho associated with both eGFR and serum calcitriol. The log transformed value of the amount of 24 hr urinary excreted Klotho significantly correlated with the eGFR (a) and serum calcitriol (b). There were significant associations between the log transformed serum Klotho levels and the eGFR (c) and between the log-transformed serum soluble Klotho levels and serum calcitriol as well (d).Back to article page
