| 1. Calcium homeostasis is determined from serum calcium, 25(OH)D, PTH and urinary calcium:creatinine ratio at clinic visits every 12 months for 1 year (2 visits) through medical record review 2. Inflammation is determined from serum high-sensitivity C-reactive protein (hs-CRP) levels measured at clinic visits every 12 months for 1 year (2 visits)through medical record review 3. Liver function is determined from serum Alanine Amino-Transferase (ALT) and Gamma Glutamyl Transferase (GGT) levels measured at clinic visits every 12 months for 1 year (2 visits)through medical record review 4.
