Figure 1

(a) The performance of six marker combinations on the testing and validation subgroup of the time to fixation breast cancer series as measured by receiver-operator characteristic (ROC) curves and area under the curve (AUC) values. The tissue quality index (TQI) was then calculated on the complete time to fixation breast cancer series. (b) TQI values of cytokeratin:pHSP27 and (c) ERK1/2:pHSP27 in relationship with increasing cold ischemic time.
