The (mean±s.d.) values of grades of frequency and sleep disturbance were compared using the Kruskal–Wallis H statistic among the three groups. Both grades for (a) frequency of skin scratching episode and (b) sleep disturbance due to skin itching were significantly different across groups (a, P<0.0001; b, P<0.0001).
