Figure 5.

Distributions of log(2) in BAC-clone hybridizations of tumor DNA from dead and alive patients versus normal reference DNA as described in Methods. The upper left and lower right quadrants represent conditions where both non-surviving and surviving patients have pronounced and less pronounced DNA alterations compared to normal reference DNA. Thus, in the upper left quadrant the non-surviving patients have pronounced and surviving patients less pronounced DNA alterations compared to normal individuals. The lower right quadrant represents opposite conditions.
