Estimates of PFS for a group of 404 patients with CLL divided into 3 risk groups: high risk (in red), 17pdel; intermediate risk (in yellow), unmutated IGHV and/or 11qdel but not 17pdel; low risk (in blue), mutated IGHV and no 11q or 17pdel. See Figure 1A in the article by Rossi et al that begins on page 1921.
