From: A prospective study examining cachexia predictors in patients with incurable cancer
Classification and regression tree (CART) analysis. The study population is divided repeatedly according to optimal cut-offs of the variables weight loss (rounded to the nearest integer), cancer type and appetite loss into subdivisions of significantly different hazard rates. Adjacent subdivisions from different branches with similar hazard rates are combined resulting in five risk-levels. Hazard ratios (HR) are reported relative to the branch with neutral risk cancer type and no or little appetite loss
