Table 7. Association of fasting serum levels of sCD26/DPP-IV with antidiabetes medications groups among type 2 diabetes patients.

Parameters	B	P-value
* SU+TZD w/wo insulin	24.0	0.760
metformin +SU+ TZD w/wo insulin	-131.6	0.120
Monotherapy with Metformin	-201.6	0.041
Non-treated	-97.4	0.085

The results are presented as unstandardized coefficients; B and (P-value) assessed using multiple linear regression adjusted for, age, race, gender, BMI, HbA1c, and duration of diabetes. Bold values are significant. B: coefficient for the relationship between the dependent variable “DPP-IV level” and the independent variable “diabetic drugs”. The positive sign of the coefficient implies a direct relationship, and the negative sign implies an inverse relationship.

*Sulfonylurea (SU), Thiazolidinedione (TZD) with or without insulin.
