Mitigating Potential Bias All the recommendations involving clinical medicine are based on evidence that is accepted within the profession. All scientific research referred to, reported, or used is in the support or justification of patient care. Recommendations conform to the generally accepted standards. The presentation will mitigate potential bias by ensuring that data and recommendations are presented in a fair and balanced way. Potential bias will be mitigated by presenting a full range of products that can be used in this therapeutic area.

Learning Objectives After active participation in the workshop participants will be able to: Identify patient factors that impact the addition of non insulin pharmacotherapy in Type 2 Diabetes. Discuss the glycemic and cardiovascular end point evidence among non insulin pharmacotherapies in Type 2 Diabetes. Apply evidence based diabetes management to individual patient care.
