Serum Mg2+ levels. A Serum Mg2+ levels according to FHH-genotype. Serum Mg2+ levels are lower in the FHH-negative than in the FHH-positive group (p < 0.001). B Discriminative accuracy of serum Mg2+ levels for classifying patients as FHH-negative or FHH-positive. The area under the ROC curve was 0.825 (95% CI: 0.709–0.941)
