Mean rARE and standard error for miRNAs in different conservational categories under different cutoffs of high expression.

The differences in rARE among the miRNA conservational categories were found to be significant with different expression cutoffs (60–90%) tested.经对60%至90%区间内的不同表达阈值（cutoff）进行测试后发现，不同微小RNA（miRNA）保守性类别之间的rARE差异具有统计学显著性。
