From: Effect of etanercept in polymyalgia rheumatica: a randomized controlled trial
Primary outcome. Polymyalgia rheumatica activity score (PMR-AS) in 20 patients with PMR and 20 non-PMR control subjects at baseline (black bars) and after (white bars) 14 days of treatment with etanercept or placebo. PMR-AS is calculated from the blood level of C-reactive protein, duration of morning stiffness, subject's assessment of pain (visual analog score (VAS)), physician's global assessment (VAS), and the subject's ability to elevate the arms (see text). Δ all values in control subjects significantly different (P < 0.0001 to 0.01) from values in patients.
