Performance for differentiation of subjects with NSCLC surviving at least four years post-surgery from those dying before four years is shown as a function of the lower accuracy limit of the additional filtering constraint applied using patients with non-squamous histology with insufficient follow up. First panel: AUC for the development subset and validation set; second panel: difference in AUC between development subset and validation set; third panel: fraction of the 9 subjects with insufficient follow up set aside for testing classified as Alive. The upper accuracy limit of the additional filtering constraint was set to 1.0 in all cases
