OS Kaplan Meier curve by AJCC v7 Stage. together with a summary of associated statistics (median OS, 3-year OS rate estimates including the corresponding two-sided 95% confidence interval intervals (calculated by Greenwood formula’s estimation of the standard deviation for rates and by Brookmeyer and Crowley technique for the median). OS censoring markers were displayed. Cox’s proportional hazards model was fit by AJCC v7 stage. Hazard ratios (HR) with 95% confidence intervals were computed with AJCC v.7 stage I as reference stratum (HR = 1.00). Log-rank test was computed at 5% significance. NE: Not Estimated. (a) NSCLC. There was a significant difference between stage (p < 0.0001). (b) Mesothelioma. There was no significant difference between stage (p = 0.70). (c) Thymic malignancies. There was a significant difference between stage (p = 0.0498).
