Apart from the “relationships with others” item, all other BPI items and the 2 HAD items improved significantly (). The effect size was very large on background pain (d = 1.7) and number of painful attacks per day (d = 1.7) items. : Numerical scale corresponding to average pain over the last 24 hours (BPI item 5). SD: standard deviation. n/day: number of painful attacks per day.
