Figure 2. Estimated probability of overall survival.

Figure 2

A: Copy number loss at position 4q21.23 (RP11-570L13) revealed strong correlations with shorter median overall survival (OS) in univariate analysis (23.9 months versus 42.6 months), P = 0.033. B: Copy number loss at position 4q21.23 (RP11-570L13) in the squamous cell carcinoma (SqCC) subgroup showed strong correlations with shorter OS (12.5 months versus 41 months), P = 0.031 C: Copy number loss at position 4q22.1 (RP11-1053C2) showed significant correlations with shorter DFS (25.8 months versus 40.3 months), P = 0.012. D: Copy number loss at position 4q22.1 (RP11-1053C2) showed significant correlations with shorter DFS in adenocarcinoma subgroup (10.0 months versus 43.1 months), P = 0.035. Survival plots for gain aberrations were faded out for the sake of clarity.
