CRP and enthesitis: Baseline demographic and clinical disease characteristics were generally similar among the pooled DISCOVER-1 and DISCOVER-2 patient population (n = 1120) and the axPsA and non-axPsA (data not shown) patient cohorts in this post hoc analysis; although, the axPsA cohort was characterized by somewhat higher proportions of patients who were male (61% vs 52%) and who had enthesitis (72% vs 65%) and dactylitis (50% vs 42%) and a higher mean CRP level (2.5 vs 1.8 mg/dl) relative to the overall pooled study population (Table 1).
