PFS and OS Kaplan–Meier plots comparing the predicted low to high risk of progression classified groups as determined by a logistic regression model for the discovery training set and external test sets of LC patients prior to treatment. Significance testing was calculated using the Mantel–Cox log-rank test. (a) PFS survival curves for the discovery training set (p < 0.0001); (b) PFS survival curves for the external test set (p < 0.01); (c) OS survival curves for the discovery training set (p < 0.0001); (d) OS survival curves for the external test set (p < 0.01).
