Table 3 Multivariate analysis of predictors for radiographic progression

From: Risk factors for radiographic progression in psoriatic arthritis: subanalysis of the randomized controlled trial ADEPT

Variable OR 95% CI Pvalue
Treatment with adalimumaba 0.21 0.10, 0.42 < 0.001
CRP (continuous) 1.16 1.01, 1.33 0.040
CRP > 0.287 mg/dla 4.31 1.42, 13.09 0.010
CRP (1.0 mg/dla 3.28 1.66, 6.51 < 0.001
CRP (2.0 mg/dla 2.29 1.12, 4.69 0.023
Modified total Sharp score 1.01 1.00, 1.02 0.002
  1. CI, confidence interval; CRP, C-reactive protein; OR, odds ratio. Separate multivariate analyses were performed for CRP (continuous), CRP > 0.287 mg/dl, CRP ≥1.0 mg/dl and CRP ≥2.0 mg/dl. For non-CRP variables, results are from the analysis with CRP > 0.287 mg/dl. All multivariate analyses also included baseline age, rheumatoid factor (yes/no), tender joint count, swollen joint count, and methotrexate use (yes/no) as variables; P > 0.05 for each. aDichotomous variables - those without a footnote annotation are continuous variables.
