44 1. Increasing T2DM prevalance& complexity of therapeutic options have led to the need f treatment guidelines. 2. These tend not to be based on -quality evidence but instead on expert opinion and/ cost concerns. 3. Most begin quite similarly ( Lifestyle then metfmin ), but differ to varying degrees on what to do next. 4. Emerging data from recent CVOT trials should lead to some modifications in guidelines -particularly in those patients with overt CVD. 5. There will also always be a need f the wise and skilled physician to choose the optimal therapeutic regimen f (and with) each patient. t
