Insulin titration: patients were to adjust insulin dose as indicated based on three consecutive, daily (morning), fasting finger-stick glucose measurements

Fasting glucose measurements	Change in insulin glargine dose
>5.6 mmol/L (100 mg/dL) (on 3 consecutive mornings)	Increase dose by 2 IU
>10.0 mmol/L (180 mg/dL) (on 3 consecutive mornings)	Increase dose by 4 IU
≤3.9 mmol/L (70 mg/dL) (at any time)	Contact study physician for insulin dose (if study physician not reached prior to next dose, dose reduced by 4 IU)

Goal was fasting glucose of 4.0–5.6 mmol/L (72–100 mg/dL)
