I would like to point out the similarity of the Figure 1 in this paper, with the previously published one from:

Treiber, T., Treiber, N. & Meister, G. Regulation of microRNA biogenesis and its crosstalk with other cellular pathways. Nat Rev Mol Cell Biol20, 5–20 (2019). https://doi.org/10.1038/s41580-018-0059-1

In Figure 5: Non-canonical biogenesis miRNAs

Did you miss this reference on the main text/caption of the Figure?
