结局指标
主要结局
Cohen-Mansfield Agitation Inventory (CMAI)
时间窗: Baseline to 12 weeks
The Cohen-Mansfield Agitation Inventory (CMAI) is a 29-item scale to assess agitation. Each item is rated on a 7-point scale of frequency, from least (1) to most frequent (7). Items are summed to calculate the CMAI total score. The CMAI total score has a range of 29-203 points; higher scores indicate more severe agitation
