SECONDARY outcome

Timeframe: Baseline to Week 12

Participants indicate the extent to which each of the 22 symptoms has disturbed them in the previous 2 weeks on a 5-item scale (0-none to 4-severe). The NSI total score is the sum of severity ratings of the symptoms. The scores are summed to yield a total score ranging from 0 to 88, where the higher the point value, the greater (more severe) the symptoms.
