Outcomes

Primary Outcomes

Changes From Baseline in Visual Analog Scale of Neurological Symptoms. - Extreme Fatigue (ANCOVA Model)

Clinically significant changes in Visual Analog Scale - Extreme fatigue. A VAS is a straight line with two end points that represent the extremes of a range. This VAS used to measure extreme fatigue has one end labeled "no fatigue" and the other end labeled "worst fatigue". The patient then marks a point on the line to indicate their current level of fatigue. The minimum score is a 0 and the maximum score is a 10. A higher score indicates a worse outcome (fatigue).
