  1. Odd ratios represent the odds of being in the ‘lower literacy’ group compared to the ‘higher literacy group’. Lower literacy is a score ≤ 3 on the final domain score
  2. Adjusted sample size: ‘understanding information’: n = 2026, ‘ability to engage’: n = 2025
  3. aModel adjusted for all subgroups variables in the table
