Variables that were found statistically significant in univariate survival analyses after Bonferroni correction, with associated P-values for the combined, ACRIN, and UW cohorts respectively. P-values in bold indicate significance with respect to the Bonferroni correction threshold of 0.05/97 = 0.0005. Median, p10, p90, and RMS, respectively, correspond to the sample median, 10th and 90th percentiles, and root mean square (quadratic mean) of the tumor SUV values.
