Hazard ratios at 1, 3 and 5 years for primary composite and secondary outcomes (cause-specific hazard models with robust standard errors for clustering in matched pairs)

Note: CCC = complex continuing care, CI = confidence interval, HR = hazard ratio, LTC = long-term care, MI = myocardial infarction, TIA = transient ischemic attack.
↵* Outcomes of stroke, MI and admission to an institution were censored for death.
