Blank square, long-term care facility case-patient; black square, community-based case-patient. Case-patients with missing responses for residence type and outcomes were excluded from analysis. *p<0.05 for long-term care facility case-patients versus community-based case-patients. †p<0.05 indicates significance between the following groups: 75–84-year age group versus 65–74-year age group, or >85-year age group versus 65–74-year age group.
