Table 2.
A Multilinear Regression Model of N-MID in DM Group Alone Revealed That β-CTX, TT3, HbA1C, and 25-OH-VitD3 Were Independent Driving Factors of the Change in N-MID. Specifically, β-CTX and TT3 Levels Were Positively Related to N-MID, While HbA1c and 25-OH-VitD3 Were Negatively Related to N-MID. These Parameters Could Explain 44.9% (R Square Was 0.449) of the Observed N-MID Change in the Current Study
