Figure 3

Weighted PCA plots for integrative sparse k-means clustering. Each point represents a patient and each class of patients is shown in a different color (blue, red, or green). (A) Dura-Cranial (Proportion of variance explained by PC1 (0.39) and PC2 (0.16)), (B) Blood-Cranial (Proportion of variance explained by PC1 (0.62) and PC2 (0.24)), and (C) Blood-Dura-Cranial integrative sparse k-means clustering analysis (Proportion of variance explained by PC1 (0.40) and PC2 (0.17)). The “true” patient class is unknown and is based on the sparse k-means clustering assignment.
