CI: confidence interval. ^#: the multivariate hazard ratios are for vaccinated subjects as compared with unvaccinated subjects and were adjusted by the following. ^¶: adjusted for sex, age, obesity, chronic lung disease, immunocompromised status and receipt or nonreceipt of influenza vaccine the previous year; ⁺: adjusted for sex, age, chronic lung disease, chronic cardiopathy, immunocompromised status, obesity and receipt or nonreceipt of influenza vaccine the previous year; ^§: adjusted for age, immunocompromised status and receipt or nonreceipt of influenza vaccine the previous year; ^ƒ: adjusted for sex, age, chronic lung disease, immunocompromised status and presence or absence of hypertension. The categorisation of age was 65–74 yrs, 75–84 yrs or >84 yrs.
