Correlation between Serum Mg Concentration and Isotopic Composition There is a lack of significant correlation between the serum Mg concentration and isotopic composition in all but one dataset between the present study and Grigoryan et al.—the exception being the T1DM group from Grigoryan et al., in which a highly significant inverse correlation was observed ( r = −0.70, p < 0.0001) ( Figure 4 ) [ 25 ].
