  • To avoid oversampling abnormal data, all BG values within a 3-h window were considered duplicates, and the earliest value was called eBG.

  • *All BG and eBG data are given in mg/dL. For an approximate conversion to mmol/L, divide by 18.

  • †Includes wide fluctuation.

  • ‡Significant change from the preceding time period.
