Clinical and genetic features of patients with CLL surveyed. Panels of the indicated disease-specific clinical, mutation, cytogenetic, and surface antigen features were compared among all 42 patients with CLL in the study. The number of patients evaluable for each feature is given, along with the number of positive samples for a given feature (when relevant for categorical variables). Gray boxes indicate unavailable information. Each patient is shown in a unique column, and samples are sorted from left to right according to frequency of cytogenetic abnormalities.
