Note: For demographic and clinical data, the cohort of 2020 was compared to children and adolescents with a diagnosis of type 1 diabetes in the two previous years 2019 and 2018 in Germany. All children and adolescents were between 6 months and less than 18 years of age at the time of diabetes diagnosis. Unadjusted values were compared via Wilcoxon's rank sum test for continuous variables and χ2‐test for dichotomous variables.
