Metformin + Sitagliptin
Participants taking metformin + sitagliptin (Januvia®/Xelevia®) as prescribed in routine clinical practice.
|Drug: Metformin Drug: Sitagliptin|
Metformin + Sulfonylurea
Participants taking metformin + sulfonylurea as prescribed in routine clinical practice. The sulfonylurea could include: gliclazide, glibenclamide, or glimepiride.
|Drug: Metformin Drug: Sulfonylurea|
Sitagliptin +/- Other Antihyperglycemic Medication
Participants taking sitagliptin +/- other antihyperglycemic medication (other than metformin) as prescribed in routine clinical practice. These other antihyperglycemic medications could include: insulin, glinides, sulfonylurea, glitazone, an alpha-glucosidase inhibitor, or combinations thereof.
|Drug: Antihyperglycemic Medication|
- Median Duration (in Months) of Initial Dual Therapy [ Time Frame: Up to 3 years ]The treatment maintenance duration corresponds to the treatment maintenance and persistence duration for dual therapy combining the same agents. Withdrawal of an agent, replacement of one agent by another or addition of a third agent is perceived as a change in treatment and, hence, the end of the treatment maintenance duration for dual therapy.
- Percentage of Participants With Strict Changes in Initial Dual Therapy [ Time Frame: Up to 3 years ]Strict changes in dual therapy were defined as withdrawal of an agent, replacement of one agent by another, or the addition of a third agent. Changes in dose level were not considered strict changes.
