Correlations of SD of HbA1c and CV of HbA1c with change percentage of brachial FMD, NO, ET-1, eGFR-Cr, eGFR-Cys C, and ACR throughout follow-up period. SD of HbA1c was positively correlated with change percentage of ET-1 and ACR, and negatively correlated with change percentage of brachial FMD, NO, eGFR-Cr and eGFR-Cys C (a). CV of HbA1c was positively correlated with change percentage of ET-1 and ACR, and negatively correlated with change percentage of brachial FMD, NO, eGFR-Cr and eGFR-Cys C (b)
