- Legend: Table shows the odds ratio of testing positive within 14 days if the case was defined as a close contact to an asymptomatic case compared to a symptomatic case. Crude shows the unadjusted ratio; + Index controls include confounders for the index case (age, sex, country of birth, and number of vaccine doses); and + Case controls additionally adjust for these confounders for the close contact. Note that this is not conditional on being tested. For full regression models and conditionality on being tested see Additional file 1: Supplementary Table 1
