Unadjusted and adjusted linear regression models were log transformed. Values shown are exponentiated to estimate the geometric mean, expressed as a percentage of change in total cost compared to the referent
Estimates are adjusted for the national (1957–1978) and Nova Scotia (1979–2015) Consumer Price Index for Health and Personal Care
Inflation was determined using year of biopsy
***p < 0.01, **p < 0.05, *P < 0.1
