Table 4. The relation of TyG index to category of CAN.

Stage	Category	No. of patients	TyG index	P value
0	T2DM without CAN	140	9.5 ± 0.2	-
1	Early CAN	7	10.2 ± 0.4	< 0.031*
2	Definite CAN	24	10.3 ± 0.1	< 0.049†
3	Severe CAN	31	10.3 ± 0.3	< 0.034‡

T2DM with CAN specified as stage 0, T2DM with early CAN as stage 1, T2DM with definite CAN were specified as stage 2, T2DM with severe CAN as stage 3.

TyG = triglyceride glucose, CAN = cardiac autonomic neuropathy, T2DM = type 2 diabetes mellitus.
