Increased blood urea nitrogen levels and compromised peripheral nerve function in patients with type 2 diabetes

Figure 1 Study diagram. eGFR: Estimated glomerular filtration rate.

Figure 2 Graphical correlations between blood urea nitrogen levels and overall peripheral nerve functional indices. Pearson’s correlation coefficient (r) and the corresponding P value were based on total data (n = 585). A: Overall nerve latency; B: Overall nerve amplitude; C: Overall nerve conduction velocity (NCV). BUN: Blood urea nitrogen.

Figure 3 Graphical correlations between blood urea nitrogen levels and functional indices of motor and sensory nerves. Pearson’s correlation coefficient (r) and the corresponding P value were based on total data (n = 585). A: Motor nerve latency; B: Motor nerve amplitude; C: Motor nerve conduction velocity (NCV); D: Sensory nerve latency; E: Sensory nerve amplitude; F: Sensory nerve NCV. BUN: Blood urea nitrogen.
