CRP and spondylitis: Secondary endpoints such as functional index (Bath Ankylosing Spondylitis Functional Index) (2.32 vs. 3.34, p = 0.021), patients’ global assessment (2.92 vs. 4.11, p < 0.001), physician global assessment (2.67 vs. 3.60, p < 0.001), spinal pain score (2.52 vs. 3.31, p = 0.025), swollen joint count (0.05 vs. 0.40, p < 0.001), morning stiffness (2.08 vs. 3.27, p < 0.001), erythrocyte sedimentation rate (28.17 mm vs. 34.25 mm, p = 0.023), and C-reactive protein (9.57 mg/l vs. 21.34 mg/l, p = 0.027) were also better in the thalidomide group.
