结局指标
主要结局
Cognitive Function as Measured by Omissions on the CPT
时间窗: Following 3 weeks of medication. The CPT task was performed at 60 minutes following alcohol or placebo beverage consumption.
Cognitive function was measured using the Continuous Performance Task (CPT). The CPT assess attention and response inhibition and the main outcome was number of omissions (the number of times the target was present, but the subject did not respond) errors in response to go and stop targets. Participants are presented with "stop" and "go" targets that appear on a computer screen. They are told to press the space bar (respond) to "go" targets and to avoid pressing the space bar when "stop" targets appear. Presented in the data table are the average number of omissions (the number of times the target was present, but the subject did not respond). Higher omission rates indicate a greater level of inattention (range 0-324).
