At the level of Ct values of our extraction methods, a highly significant, very strong positive correlation was demonstrated between the miRNeasy kit and the TRIzol and Universal kits (miRNeasy/Universal p < 0.0001, r = 0.980; TRIzol/miRNeasy p < 0.0001 r = 0.959), and a highly significant, very strong positive correlation was found between the TRIzol and Universal kits (TRIzol/Universal p = <0.0001, r = 0.965) ( Figure 3 ). 3.2.
