Linear correlations of fasting plasma glucose and HbA1c with serum magnesium in the whole population from the cross sectional case-control study.

<p>White circles, non-diabetic patients (fasting plasma glucose: r = −0.155, p = 0.059; HbA1c: r = −0.302, p = 0.002); black circles, type 2 diabetic patients (fasting plasma glucose: r = −0.484, p<0.001; HbA1c: r = −0.389, p = 0.010).
