Change in plasma creatinine concentrations (A), body weight (B), blood bicarbonate (HCO₃ ⁻) concentration (C), and potassium concentrations (D) over time in cats with ionized hypercalcemia at diagnosis of azotemic CKD (BHCa, n = 11) and cats that developed ionized hypercalcemia during the course of CKD (RDHCa, n = 10) that were transferred to a moderately protein and phosphate restricted diet. Reference intervals are shown with a shaded area where applicable. Because of a very small number of data points occurring after the 6 month time point in the RDHCa group, only data up until 6 months were included in the model for this group
