Bland-Altman plot of Metastatic Assay scores on the development and Xcel™ microarray platforms prior to (A) and post (C) linear bias correction. Scatter plot of Metastatic Assay scores from prostate cancer patients (n = 55) processed on the development and Xcel™ microarray platforms prior to (B) and post (D) linear bias correction. The dotted line is the estimated regression line. The solid line is the line of equality. Each open circle represents the assay score of the same sample profiled on the development and Xcel™ microarray platforms. Open circles connected by a solid line represent replicate samples
