Members of Paediatric Tuberculosis Network European Trials Group (ptbnet) were invited to share COVID-19 morbidity information during the study period. 18 year old patients and younger with a RT-PCR confirmed SARS-CoV-2 infection in any clinical sample (respiratory tract, blood, stool, or cerebrospinal fluid) were eligible. The authors used non-parametric two-tailed Mann-Whitney U tests for continuous variables and $X^2$ or Fisher’s exact tests for categorical variables. Case-fatality rate 95% CI was calculated with Wald method.
