However, the pathway regarding the LC-NE system (from NE, HRV parameter to TCM-based liver function) was not supported; NE had a marginally significant association with the LF/HF ratio ( β = 0.187, t = 1.840, p = 0.066) and there was no significant relationship between the LF/HF ratio and TCM-based liver function ( β = −0.039, t = −0.398, p = 0.690) ( Figure 2 ).
