Strain comparison: Basal plasma and urine cations. The results of the strain comparison for (A) basal plasma Mg²⁺ and (B) basal plasma Ca²⁺ are shown (median mmol/L ± 95% CI). LM/Bc mice have inherently lower plasma Mg²⁺ and Ca²⁺ than either the SWV (*p < 0.05) or the C57BL/6J strain (***p < 0.001). The results of the strain comparison for (C) basal urinary excretion of Mg²⁺ and (D) basal urinary excretion of Ca²⁺ (D) are also shown (µmol/24 h ± 95% CI). Urinary excretion of Mg²⁺ in LM/Bc was significantly higher than SWV (**p < 0.01) but did not differ from C57BL/6J. However, urinary Ca²⁺ excretion in LM/Bc mice was significantly higher than in both SWV (*p < 0.05) and C57BL/6J (**p < 0.01) mice.
