Statistical methods / analysis
Analyses will be performed using SPSS (PASW version 18). Statistical significance will be set at p<0.05. Continuous variables will be analysed by student t-test and analysis-of-covariance (ANCOVA), and categorical variables will be analysed by Chi-square test. glucose curves will be analysed using standard deviation (SD, coefficient of variation (CV), and interquartile range (IQR) as described in Bergenstal 2013 J Diabetes Sci Tech 7 (2), 562-78.)
