Risk stratification across classification pipelines and prognostic signatures. Comparison of all hazard ratios (measure of risk stratification) and corresponding p-values from Cox proportional hazard ratio modeling on (A) HG-U133A platform, (B) HG-U133 Plus 2.0 platform. The hazard ratio is represented by the size and colour of the dot and the background shade represents the p-value. Further the difference between hazard ratios on HG-U133A and HG-U133 Plus 2.0 were visualized (C). A positive value (blue) represents higher log2 hazard ratios in HG-U133 Plus 2.0 and a negative value (red) represents higher in HG-U133A.
