* Hazard ratios are relative to permanent care home admissions as the reference category.
** Hazard ratios are relative to age 65–79 years as the reference category.
*** First quartile is least deprived; fourth quartile is most deprived. Hazard ratios are relative to the first quartile as the reference category.
**** Hazard ratio is relative to males.
