Fig. 1From: Putative markers for the detection of early-stage bladder cancer selected by urine metabolomicsScore plot of PCA. Each point represents a profile of 922 compounds. The value of the first principal component of the PCA goes on the horizontal axis, and the value of the second principal component goes on the vertical axis. This unsupervised analysis captures 0.491 variation between metabolic profiles (R2X = 0.491)Back to article page
