To compare glycemic goal achievement (HbA(1c) < 7%) in type 2 diabetes patients receiving initial metformin plus pioglitazone combination therapy and initial metformin monotherapy augmented with pioglitazone in a cohort follow-up study. ⋯ Initial combination therapy patients are more likely to achieve glycemic control than sequential therapy patients, especially for patients with baseline HbA(1c) > 9%. This study is limited by the relatively small sample size and the frequency of HbA(1c) reporting. Future research could examine goal achievement using a larger sample and more complete laboratory data to confirm these findings.
