Type I Interferons Are Associated with Subclinical Markers of Cardiovascular Disease in a Cohort of Systemic Lupus Erythematosus Patients
Figure 1
Plot of the first two principal component loading vectors.
Each point represents one of the five IFIGs. Proximity of points illustrates the groupings of the IFIGs with respect to the principal components. The x-axis is the principal component factor loading for the first principal component (representing the coefficient for each IFIG in the linear combination as the principal component); the y-axis is the principal component factor loading for the second principal component. The first component can be interpreted approximately as the sum of information from MX-1, IFI44L, IFIT1, and IFI44. The second component can be interpreted approximately as the difference between the sum of (IFIT1 and IFI44) and the sum of (MX-1 and IFI44L).
