		n = 30

For categorical variables n (%) is presented. For continuous variables mean (SD)/median (min; max)/(95% confidence interval for mean)/n = is presented. For comparison over time, Fisher’s non-parametric permutation test for paired observations was used for continuous variables. The evaluation of questions of the flash glucose monitoring/continuous glucose monitoring were expressed on a visual analogue scale with lowest value (0) meaning Not true at all and highest value (10) meaning completely true.
