Statistically significant ORs (where the 95% CIs do not include 1 before rounding to one decimal place) are shown in bold.
*ORs adjusted for age group and sex.
†ORs adjusted for age group, sex and unique participant identifier.
‡Analyses for osteoarthritis excluded those younger than 60 years, as data on osteoarthritis treatment were only collected in those aged 60 or over.25a
