Combining insulin with metformin or an insulin secretagogue in non-obese patients with type 2 diabetes: 12 month, randomised, double blind trial.

At the end of treatment, the concentrations of self monitored plasma glucose appeared lower before and after breakfast in the metformin plus insulin group than in the repaglinide plus insulin group; however, these differences in self monitored plasma glucose did not reach statistical significance (before breakfast −0.54 mmol/l, 95% CI −1.10 to 0.01, P=0.055; 90 minutes after breakfast −0.98 mmol/l, 95% CI −1.96 to 0.00, P=0.051; fig 4).
