Figure 3From: Quality assessment and data handling methods for Affymetrix Gene 1.0 ST arrays with variable RNA integrityCharacteristics of genes most affected by RNA degradation. Comparison of samples that either passed or were flagged during QC. a) Fold change distribution of annotated transcript clusters comparing samples that were flagged vs. samples that passed QC b) Gene lengths of uniquely identified genes. Expression signal significantly increased (Up) or decreased (Down) with respect to the ‘Unaffected’ group, judged using a Mann-Whitney test. Adjusted p-value ≤ 0.01, |fold change| > 2.Back to article page
