*CAIX was analyzed using the minimum value across cores. All other biomarkers were analyzed using the maximum value across cores.

The kappa statistic is reported for B7-H1, whereas the concordance correlation coefficient (CCC) is reported for B7-H3, survivin, Ki-67, CAIX, and IMP3; the median (minimum, maximum) statistic from the 500 bootstrap samples is provided.
