Figure 7From: Quality assessment and data handling methods for Affymetrix Gene 1.0 ST arrays with variable RNA integrityVenn diagram of unique differentially expressed genes (tumour vs. normal) with adjusted p-values ≤ 0.01 for the four best-performing methods. A - removing quality-flagged arrays before analysis. B - applying SVA to batch corrected data. C - ComBat used to correct for batch and quality. D - Array weights included in the linear model.Back to article page
