There was a weak positive association between NmU expression and insulin levels during the liquid meal test (all subjects: incremental AUC, r = 0.363, p = 0.045; patients without T2D: incremental AUC r = 0.794, p = 0.024; 60 min r = 0.709, p = 0.044; 120 min r = 0.661, p = 0.045). Here, INS is linked to type 2 diabetes mellitus.
