The regression coefficient β and P values for potential determinants (X) i.e. Gender. S. Creatinine and FePO4 of FGF23 was positively associated and changes in response to FGF23 levels in healthy individuals. It was calculated by multiple regression analysis in 80 subjects and R2 showing good regression of FGF23 i.e. 59.8%. FePO4, fractional excretion of phosphate. Significant P values are shown in bold.
