  1. 1: Mean % Interference in the Rapid Recovery group is significantly lower than the other two groups, with no difference between Delayed and Minimal recovery groups by virtue of overlapping confidence intervals
  2. 2: Mean % Interference / mean pain severity is significantly different across all groups
  3. 3: Mean % Interference is significantly higher in the Minimal recovery group than the other two groups, with no difference between the Rapid and Delayed groups
