  Mean of absolute differences between glucose values obtained at exactly the same time of day on two consecutive days under standardized conditions.

2) Page 58, Table 3, item 9B, MODD _d , col. 2 should read:

  Mean of absolute differences in glucose between any value and the value exactly d x 24 hours later, calculated for each observation in a time series where data are available.

3) Page S-59, Table 3. Item 12, Hyperglycemia Index

  Column 1: Hyperglycemia Index, e.g., with parameters ULTR = 140 mg/dL, a = 1.1, c = 30, n = total number of glucose observations

  Column 2: Weighted average of hyperglycemic values (for all Glucose > ULTR),

  = Σ [(Glucose _i – ULTR) ^a /c]/n.

4) Page S-59, Table 3. Item 13, Hypoglycemia Index

  Column 1: Hypoglycemia Index, e.g., with parameters

  LLTR = 80 mg/dL, b = 2.0, d = 30,

  n = total number of glucose observations

  Column 2: Weighted average of hypoglycemic values (for all Glucose < LLTR),

  = Σ [(LLTR - Glucose _i ) ^b /d]/n.

5) Page S-59, Table 3. Item 15, Low Blood Glucose Index (LBGI)

  Column 1: Low Blood Glucose Index (LBGI)

  Column 2: For glucose values <112.5 mg/dL,LBGI = 22.77 {Σ [log_e(Glucose _i )^1.084 – 5.381]²/n}.

6) Page S-59, Table 3. Item 16, High Blood Glucose Index (HBGI)

  Column 1: High Blood Glucose Index (HBGI)

  Column 2: For glucose values ≥112.5 mg/dL, HBGI = 22.77 {Σ [(log_e(Glucose _i )^1.084 – 5.381]²/n}.

7) Page S-59, Table 3. Item 17, Glycaemic Risk Assessment Diabetes Equation (GRADE)

  Column 1: Glycaemic Risk Assessment Diabetes Equation (GRADE)

  Column 2: Average transformed glucose values

  GRADE = Median {min[50, 425{log₁₀[log₁₀(Glucose _i /18)] + 0.16}²]} when Glucose _i is in mg/dL

8) Page S-60, Figure 2 and legend. We have modified the figure and its legend.

9) Page S-66. Appendix 1.

  GRADE Col. 2 (Definition) should read:

  Glycaemic Risk Assessment Diabetes Equation: weighted average of glucose values, giving greater penalties to hypoglycemia than hyperglycemia, and to more severe departures from the target level of 90 mg/dL.

10) Page S-66. Appendix 1.

  MODD Mean absolute daily differences in glucose values at the same time of day on two consecutive days.

11) Page S-66. Appendix 1. The following line has been added below MODD _d :

  n total number of glucose values (including hypo-, eu-, and hyperglycemic).
