"Absolute" indicates the total number of successful sequencing reads, while "count" or "distinct" indicates the number of different sequences.

^aR = reliable, nR = non-reliable, S = significant, nS = non-significant, RS = reliable and significant, RnS = reliable and non-significant, nRS = non-reliable and significant, nRnS = non-reliable and non-significant.
