Figure 7From: Cancer detection and biopsy classification using concurrent histopathological and metabolomic analysis of core biopsiesPrincipal components analysis of kidney biopsies to distinguish cancer tumor from benign biopsies. The metabolites identified as significant (P ≤ 0.05) between cancer tumor-containing and benign kidney biopsies by matched pairs t-test were used to construct the principal components analysis. Blue, cancer tumor samples; yellow, benign samples. The six nephrectomy patients are each indicated by a shape: circle, patient 1; square, patient 2; upward triangle, patient 3; downward triangle, patient 4; left pointing triangle, patient 5; right pointing triangle, patient 6.Back to article page
