Table 3 Correlation of HbA1c and BMI with disposition index and Matsuda’s insulin sensitivity index (n = 68)

From: Improvement of beta-cell function in conjunction with glycemic control after medical nutrition therapy in newly-diagnosed type 2 diabetes mellitus

 

At baseline (A)

After medical nutrition therapy (B)

Difference between A and B

HbA1c and disposition index

-0.61 [-0.74 to -0.44] (P < 0.001)

-0.68 [-0.79 to -0.53] (P < 0.001)

-0.07 [-0.22 to 0.11] (P = 0.42)

HbA1c and Matsuda’s insulin sensitivity index

0.07 [-0.17 to 0.30] (P = 0.57)

-0.01 [-0.25 to 0.23] (P = 0.95)

-0.08 [-0.30 to 0.15] (P = 0.49)

BMI and disposition index

-0.02 [-0.25 to 0.22] (P = 0.90)

-0.02 [-0.25 to 0.22] (P = 0.90)

0.00 [-0.24 to 0.25] (P = 0.99)

BMI and Matsuda’s insulin sensitivity index

-0.58 [-0.72 to -0.40] (P < 0.001)

-0.52 [-0.68 to -0.32] (P < 0.001)

0.06 [-0.07 to 0.19] (P = 0.35)

  1. Data are correlation coefficients [95% confidence intervals] (P values). BMI and HbA1c levels were those measured at the same time point as the disposition index and Matsuda’s insulin sensitivity index.
