Figure 3. Kaplan–Meier cumulative survival functions for the four patient groups identified jointly using the k-means clustering solution (chromosome 3) and a simple thresholding condition on chromosome 8q. Group 1 represents disomy 3 and disomy 8 (n=220), group 2 represents monosomy 3 and disomy 8 (n=113), group 3 represents disomy 3 and polysomy 8 (n=104), and group 4 represents monosomy 3 and polysomy 8 (n=165).
