Susceptibility analysis: Secondary attack rates (SAR) of household contacts of children, adolescents and adults (top) as well as odd ratios (OR) (bottom) for SARS-CoV-2-infection among children and adolescents when compared to adults; wild-type, alpha variant, delta variant. To better visualize the point estimates of SAR, 95% confidence intervals are omitted. A (left): all included studies, B (right): Danish studies only [46, 70, 71]. Red bars are statistically significant from 1 on a 95% level. Note: HHC: household contact, IC: index case, NV: non-vaccinated, V: vaccinated.
