  1. The p-values in the first column are calculated using Log Rank (Mantel-Cox) test for equality of survival distributions for the different levels of GASC1 (significant p-values in bold). The p-values in the second column in the squared brackets are calculated using Fisher’s exact test to examine if there is a difference in proportion of GASC1 negative and positive cases in groups of different clinical parameters. n – number of cases.
