Duration of T2DM was significantly shorter (2 (1–5) vs 5 (3–10) years, p < 0.001) with less insulin requirement and less diabetes-related complications (7.2% vs 19.8%, p < 0.001) and significantly lower median DiaRem score (4.0 (IQR 2.0–6.0) vs 12.0 (IQR 5.0–16.0), p < 0.001). Here, INS is linked to type 2 diabetes mellitus.
