Heat map − grade of malignancy. The scaled expression of the differentially expressed microRNAs for 111 samples and the relationship among the samples in terms of microRNAs found to be differentially expressed for the malignancy grade factor; Significance Analysis of Microarrays (SAM) test; the colour scale illustrates the relative expression level of a microRNA across all samples: green colour represents an expression level below the mean and red colour represents an expression level above the mean. MicroRNAs are mostly up-regulated in the grade III group in comparison with the grade II group
