  1. Notes: estimates for SES variables obtained from multinomial logit regression (adjusted probabilities are adjusted for age groups, year and comorbidities). This Table should be read as follows: e.g., for individuals from the US living in the lowest quintile (Q1) income area, the adjusted probability of undergoing a CATH is 0.1374, controlling for age, sex, comorbidities and year. The 'no treatment' category is obtained by simple subtraction; hence it does not include any indication about statistical significance.
  2. *Estimate significantly differs from at least one other quintile's estimate at p ≤ 0.05.
