Categorical variables were reported as number (percentage) and analyzed using the chi-square test. Continuous variables with non-normal distribution were reported as median (lower quartile 25%, upper quartile 75%) and analyzed using Wilcoxon/Kruskal–Wallis tests unless otherwise noted. Continuous variables with normal distribution were reported as mean (standard deviation) and differences between groups were determined using a one-way ANOVA.
CGM, continuous glucose monitor, CV, coefficient of variation; HCL, hybrid closed loop.
