  1. The classifier training set included 223 patients diagnosed with lung cancer and 76 patients diagnosed with benign disease. The table lists clinical and demographic factors for all patients in the training set as well as characteristics of the lung cancer positive and patients with benign disease. The p-value for race is calculated for Caucasian versus non-caucasian.
