Performance Comparison of MSI methods in Prostate Cancer. Specimens are categorized as either MMR-deficient (n = 29) or MMR-intact (n = 62) based on targeted deep sequencing of DNA mismatch repair genes. Ovals specify false negative results. Error bars show mean and standard deviation. The dashed lines indicate the threshold delineating MSI-positive from MSI-negative. Specimens above the lines are interpreted as MSI-positive and specimens below the lines are interpreted as MSI-negative. NOTE: Large panel NGS has a lower threshold for positivity (> 0.20) than small panel MSI assays (MSI-PCR and MSIplus) that measure only selected highly-discriminatory loci. These thresholds have been validated as described in the methods. Asterisk indicates single false positive by Large Panel NGS (sample C03)
