Classification of symptomatic and asymptomatic RP against SUV95 and V30. Recursive partition analysis for classification of RP symptoms using pre-treatment SUV95 and V30 for N = 100 lung cancer patients results in 3 cohorts. The optimal partition derives from classifying patients with pre-treatment SUV95 > 0.949 or V30 > 27.14 as symptomatic, and those with SUV95 < 0.949 and V30 < 27.14 as asymptomatic. The joint classification tree results in sensitivity = 98% and specificity = 37%.
