|
BASDAI subject asessment of discomfort, pain and fatigue measured using a 100 millimeter Visual Analog Scale; range: 0=none to 100=very severe.
Normalized net incremental area under the curve (AUC) = area between baseline and the BASDAI curve as a function of time (randomization to Week 12); computed using the linear trapezoidal method.
