Logistic multivariable regression models of influenza (model 2) in relation to the different dimensions of physical proximity and exposure to disease or infections in a national case–control study covering 1 July 2006 to 31 December 2019
| Dimensions of physical proximity and exposure to diseases or infections | Influenza | ||
| ORs with 95% CI* | |||
| All | Influenza A | Influenza B | |
| Physical proximity | |||
| 3rd vs 2nd and 1st | 1.12 (1.07 to 1.18) | 1.11 (1.09 to 1.22) | 1.04 (0.95 to 1.15) |
| 4th vs 2nd and 1st | 1.54 (1.45 to 1.62) | 1.58 (1.48 to 1.68) | 1.42 (1.27 to 1.59) |
| Exposure to diseases or infections | |||
| 2nd vs 1st | 1.29 (1.23 to 1.35) | 1.27 (1.20 to 1.35) | 1.34 (1.21 to 1.47) |
| 3rd vs 1st | 1.27 (1.20 to 1.34) | 1.28 (1.20 to 1.36) | 1.24 (1.11 to 1.38) |
| 4th vs 1st | 1.54 (1.44 to 1.64) | 1.57 (1.46 to 1.69) | 1.43 (1.24 to 1.64) |
