Graphical correlations between lnAUCgla and overall peripheral nerve functional indices in both the T2D/OB group (n = 174) and the T2D/non-OB group (n = 480). T2D type 2 diabetes, T2D/OB patients with T2D and obesity, T2D/non-OB patients with T2D and nonobesity, AUCgla area under the curve for glucagon, lnAUCgla natural log-transformed AUCgla, NCV nerve conduction velocity
