*: mean, within subject, difference between baseline and 10 weeks. Includes only subjects checking BG at least 3.5 times per day on average. # Percentage of BG readings within a time window of 5–8 am that were < 5.3 mmol/L. Average of within subject changes from baseline. To convert mmol/L to mg/dL, multiply by 18.0182. %pts: percentage points; BG: blood glucose; RIR: readings in range
