- Legend: Table shows the odds ratio of being asymptomatic if your assumed infector was asymptomatic compared to symptomatic. Crude shows the unadjusted ratio; + Case controls include confounders for the secondary person (age, sex country of birth and number of vaccine doses); and + Index controls additionally adjust for these confounders for the index person. Note that this is not conditional on being tested. For full regression models and conditionality on being tested see Additional file 1: Supplementary Table 3.
