Logistic regression analysis examining impact of test type and result type on perception that the test result means ‘no risk’
| Proportion answering ‘no risk’ in each subgroup % (95% CI) (n=1204) | Result means ‘no risk’ of future infection OR (95% CI) | ||
| Mutually adjusted (n=1204) | Adjusted for demographics* (n=1179) | ||
| Test type | |||
| Antibody (n=603) | 9.8 (7.5 to 12.4) | Ref | Ref |
| Immunity (n=601) | 19.1 (16.1 to 22.5) | 2.77 (1.48 to 5.17) | 2.91 (1.52 to 5.55) |
| Result type | |||
| Test (n=354) | 15.5 (11.9 to 19.7) | Ref | Ref |
| Certificate (n=444) | 15.5 (12.3 to 19.3) | 0.99 (0.50 to 2.00) | 0.96 (0.47 to 1.99) |
| Passport (n=406) | 12.3 (9.3 to 15.9) | 1.22 (0.63 to 2.38) | 1.24 (0.62 to 2.48) |
| Test by result interaction | |||
| Certificate by immunity result | 0.98 (0.42 to 2.27) | 1.00 (0.42 to 2.40) | |
| Passport by immunity result | 0.47 (0.20 to 1.12) | 0.46 (0.19 to 1.12) | |
