Native T1 value was positively associated with the duration of diabetes in univariable correlation analysis (R = 0.439, P = 0.006, Figure 4(a)) but not in multivariable correlation analysis when adjusted for insulin, age, height, weight, BMI, BSA, systolic blood pressure, and diastolic blood pressure (R = 0.157, P = 0.548). Here, INS is linked to diabetes mellitus.
