Bladder cancer predictions of reviewed panel and P3 panel. BCs were represented by red blocks and non-BCs by grey blocks. The condition row presents the true status of samples while others display predictions made by panels. A 4-fold cross-validation process was applied so that 4 predictions were made for every sample by every panel. The high of red blocks represents the proportion of the sample being predicted as BC by the corresponding panel in the cross-validation process
