MA-plot of distance between the microRNA expression profile of each sample and the average expression profile of each subgroup. Large values of M correspond to samples that are far more similar to the average expression profile of subgroup 1 than subgroup 2. Large values of A correspond to samples that differ from the average expression profile of both subgroups. The dashed horizontal line (y = 0) indicates samples that are equidistant from both cluster centers. A square indicates a sample from a patient all of whose samples are from cluster 1. A circle indicates a sample from a patient all of whose samples are from cluster 2. A triangle indicates a sample from a patient whose samples are from both cluster 1 and cluster 2
