  1. SD = standard deviation; ICC = Intraclass correlation; N.A. = Not Applicable; Gwet's AC = Gwet's agreement coefficient
  2. Tested by paired t-test; EQ-5D-5L dimension responses of moderate, severe and very severe were grouped into the ‘with limitation’ category; Ceiling for EQ-5D-5L score = 1; Floor for EQ-5D-5L score = 5
