Cumulative distribution of miRNA coefficient of variation (CV) values. The cumulative distribution of miRNA CV values in the neuroblastoma sample set when no normalization is applied (blue), stable RNA control (RNU24, RNU44, RNU58A and RNU6B) normalization is applied (red), mean expression value normalization is applied (green) or normalization with miRNAs/small RNA controls resembling the mean expression value (Z30, RNU24, miR-361, miR-331 and miR-423) is applied (purple).
