Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Metformin | Standard diet and glucose self-monitoring education. Initiated on Metformin 500 BID if medication naïve, or continued on their current dosage of Metformin if taking it prior to pregnancy. Dosage titrated to a maximum of 2250 mg/day based on review of self-reported fasting and post prandial glucose values during visits. .NPH Insulin treatment added for those unable to achieve glycemic control with Metformin alone. | 0 | 14 | OG000 |
| Group 2 | Insulin | Standard diet and glycemic monitoring education. Initiated on weight-based Regular and NPH insulin at a total dosage of 0.7units/kg in the first trimester or 0.8units/kg in the second trimester divided as 2/3 of the total dosage (with 2/3 given as NPH and 1/3 given as Regular) administered before breakfast and 1/3 of the total dosage (with 1/2 given as NPH and 1/2 given as Regular) administered with dinner. Dosage titrated during visits to achieve optimal glycemic control with fasting values \<90 mg/dL and 1-hr post prandial values \< 130 mg/dL. | 0 | 14 | OG001 |
