Cumulative frequency of p-value of real and background miRNA precursors. Three different lengths were examined: 100, 200, and 300 nt. At a threshold of ≤ 0.05, there was small difference in frequencies for real and background of length 100 nt. However, with increase in length of background precursors, the p-value declined drastically.
