Figure 3From: Integrated analysis of independent gene expression microarray datasets improves the predictability of breast cancer outcomeComparison of profiles from individual and combined datasets. ROC curves were built with testing SEP scores obtained from two individual datasets and their combination. The size of expression profiles was increased from 1 to 100 one by one. Median areas were summarized from 10,000 re-samplings. Size-weighted average areas achieved by the combined dataset (red line) were generally larger than the corresponding areas achieved by individual datasets (blue line).Back to article page
