Change From Open-label Baseline in Modified Scale for the Assessment of Negative Symptoms (SANS-18) Total Score at Week 10 Open-label Phase, Last Observation Carried Forward (LOCF)
기간: Open-label Baseline and Week 10 Open-label Phase
The SANS was modified by eliminating the global and attention items; the score of the remaining non-global items is referred to as the SANS-18 total score. Each of the 18-items is scored on a scale from 0 (not at all) to 5 (severe) with a total scoring range of 0 to 90. Higher scores indicate more impairment.
