Association between renal function and circulating intact FGF23 in human, feline, and canine CKD patients as well as in experimental murine CKD. Intact serum FGF23 and estimated glomerular filtration rate (eGFR) as well as serum creatinine levels are correlated in human (n = 16), canine (n = 34), and feline (n = 38) CKD patients as well as in mice with experimentally induced CKD (n = 50). Insets show Spearman rank correlation coefficients.
