highly significantp ≤ 0.0001
The impact of each factor on the model is considered highly significant ( p ≤ 0.0001), and according to the F-values, the order of the influence of extraction conditions on LRM-ELN yield is as follows: A (concentration of PEG6000) > B (relative centrifugal force) > C (incubation time), indicating that the concentration of PEG6000 is the key factor affecting the yield.
