The utility of a classificatory decision tree approach to assist clinical differentiation of melancholic and non-melancholic depression

摘要

Background: Studies suggest that differentiating melancholic from nun melancholic depressive disorders is advanced by use of illness course as well as symptom variables but, in practice, potentially differentiating variables are generally positioned as having equal value, judging that differentiating features are more likely to vary in their signal intensity, we sought to determine the number of features required to effect differentiation and their hierarchical order.
