Comparisons between FGF23, Klotho and sclerostin pre and post-transplant will be made by paired t-test, assuming normal distribution. Associations between FGF23, Klotho and sclerostin levels with demographic data and biochemical parameters in the two time-points will also be accessed with t-test, with Pearson test and linear regression, whenever applicable. A multivariable analysis will be executed to control for confounders (age, gender, diabetes, PTH, renal function, immunosuppressive regiments). Associations between FGF23, Klotho and sclerostin with bone turnover, mineralization and volume will be explored with regression models. The potential effects of FGF23 or sclerostin with CV health will be explored using regression models.
