Pre-influenza season hazard ratios (HR) for all-cause mortality comparing vaccinated beneficiaries with unvaccinated beneficiaries as the reference, using different combinations of comorbidities, healthcare use, and ADL dependency predictors as adjustment sets.

Comorbidities	0.62	0.61 – 0.64
Healthcare use	0.61	0.59 – 0.62
ADL dependency predictors	0.68	0.66 – 0.70
Comorbidities & healthcare use	0.66	0.64 – 0.67
Comorbidities & ADL dependency predictors	0.67	0.66 – 0.69
Healthcare use & ADL dependency predictors	0.67	0.66 – 0.69
