Levels of 4 miRNAs in plasma from patients with type 1 narcolepsy, type 2 narcolepsy and idiopathic hypersomnia. The 4 panels show levels of 4 miRNAs: miR-30c, miR-130a, miR-26a, and let-7f in plasma from patients with type 1 narcolepsy (NC), type 2 narcolepsy (NwC), and idiopathic hypersomnia (IH).
