OPLS variable importance in projection (VIP) model 3. The numerical value for a variable represents an estimation of its importance in the model, that is, to what grade it discriminates between the two groups of patients. Whiskers illustrate the upper limit of bootstrapped confidence intervals. Acc activity: accumulated disease activity. aCL: anti-cardiolipin. BMI: body mass index. CIC: circulating immune complexes. CRP: c-reactive peptide. ESR: erythrocyte sedimentation rate. HAQ: health assessment questionnaire. HDL: high-density lipoproteins. IL2sR: soluble receptor of interleukin-2. IMT: carotid intima media thickness. LDL: low-density lipoproteins. ox-LDL: oxidized LDL. PAI: plasminogen activator inhibitor-1 mass. TG: triglycerides. tPA: tissue plasminogen activator. vWF: von Willebrand factor.
