At baseline, the mean (±SE) score for ‘sleep quality’ was 9.7 (±0.30), which was considered a moderate severity level (score = 10). However, a significant improvement was seen on day 1 of treatment (p = 0.0001), with a mean score of 7.3 (±0.37), which was closer to mild severity level (score = 6). At the last dose administered sleep quality improved by 72.5% (Table 6).
