5. Evidence in children:All key questions and all included medications For children, the strength of evidence was insufficient to make conclusions for all included medications
The remaining slides address evidence in adults 5
6. Key Question 1 What is the comparative efficacy and effectiveness of newer diabetes medications, TZDs, and drug combinations (administered as fixed dose combination products or dual therapy) for children and adults with diabetes mellitus? 6
7. Health Outcomes Some studies of these medications reported some health outcomes such as all-cause mortality or number of people with macrovascular disease among secondary outcomes or among adverse events, but overall evidence was insufficient to determine how the newer diabetes medications and combinations compare with other treatments for their impact on health outcomes.

37. FDCPs and Dual Therapy:Actoplus Met® or dual therapy with pioglitazone and metformin 37 -Evidence was limited to one large trial (N=600) comparing Actoplus Met® with component monotherapies and a 15 month trial comparing dual therapy with pioglitazone and metformin to monotherapy with either that reported very little harms information.-Evidence was limited to one large trial (N=600) comparing Actoplus Met® with component monotherapies and a 15 month trial comparing dual therapy with pioglitazone and metformin to monotherapy with either that reported very little harms information.
38. FDCPs and Dual Therapy:Janumet® or dual therapy with sitagliptin and metformin 38
39. Key Question 3 Are there subgroups of patients based on demographics (age, racial groups, gender), comorbidities (drug-disease interactions, obesity), or other medications (drug-drug interactions) for which newer diabetes medications, TZDs, and drug combinations (administered as combination products or dual therapy) differ in efficacy/effectiveness or frequency of adverse events? 39
40. Key Question 3 40
41. Conclusions All of the included medications were efficacious for reducing HbA1c and none of the newer medications appear to cause weight gain. Little data were available to evaluate the long-term effectiveness of the newer medications compared with more established treatments, limiting our ability to determine how to best incorporate newer medications into clinical practice. 41
