Coronary Artery Calcification Is Related to Inflammation in Rheumatoid Arthritis: A Long-Term Follow-Up Study

Figure 3

OPLS loading plot model 1. The dots represent the loadings of the single variables in each of the two vectors (latent variables) in the OPLS model. This plot displays how the variables are related to each other and to CAC status. The distance from origo is proportional to the importance in the OPLS model. Acc activity: accumulated disease activity. BMI: body mass index. CAC: coronary artery calcification. CIC: circulating immune complexes. DAS28: 28-joint disease activity score. ESR: erythrocyte sedimentation rate. FU: follow-up. HAQ: health assessment questionnaire. HDL: high-density lipoproteins. HT: hypertension. IL2sR: soluble receptor of interleukin-2. IMT: carotid intima media thickness. LDL: low-density lipoproteins. PAI: plasminogen activator inhibitor-1 mass. SJC: swollen joint count. VAS: visual analogue scale.
