Free and fixed‐ratio combinations of basal insulin and GLP‐1 receptor agonists versus basal insulin intensification in type 2 diabetes: A systematic review and meta‐analysis of randomized controlled trials

A meta-analysis is presented of randomized controlled trials (RCTs) comparing free or fixed combinations of a glucagon-like peptide-1 receptor agonist plus basal insulin versus insulin intensification on metabolic control in patients with type 2 diabetes. Electronic databases were searched for RCTs assessing changes in HbA1c, proportion of patients at HbA1c target of 71%, P < 0.001). Results did not differ in either the free or fixed combination subgroups. Combination strategies, either free or fixed, represent a good option for intensifying basal insulin therapy in patients with type 2 diabetes who need amelioration of glycaemic control.
