Table 2

Sensitivity and accuracy in signal detection. TaqMan® Gene Expression Assays calls were used as the "ground truth" to calculate the True Positive, True Negative, False Positive, False Negative, True Positive Rate (TPR) and False Positive Rate (FPR) as described in Methods. Detection thresholds for each platform were defined according to corresponding manufacturer's recommendations and described in Methods. Results are shown as sum of the Brain, Liver and Lung tissues
