Plasma total magnesium concentration in cats with IRIS stages 2–4 CKD. Significantly higher plasma magnesium concentrations were observed in cats with IRIS stage 4 CKD (mean, 3.01 mg/dL; SD, 1.206; P < .001) compared with cats with IRIS stage 2 (mean, 2.04 mg/dL; SD, 0.261) and 3 CKD (mean, 2.04 mg/dL; SD, 0.361). The prevalence (95% CI) of hypomagnesemia was 9% (4–14), 18% (7–29), and 10% (0–27), respectively, in IRIS stages 2, 3, and 4. The prevalence of hypermagnesemia was significantly higher in IRIS stage 4 (50%; 95% CI, 19–81; P < .001) compared with IRIS stages 2 (3%; 95% CI, 0–6) and 3 (6%; 95% CI, 0–13). The boxes represent medians with 25th and 75th percentiles, the whiskers represent ranges. Dotted lines mark the lower and upper limits of the reference interval for plasma total magnesium (1.73‐2.57 mg/dL)
