Spearman's analysis (Table 2, Figure 2a) revealed that ATGL level was inversely associated with diabetes duration (R2 = −0.150, p = 0.046), UACR (R2 = −0.283, p < 0.001), 24 h-UTP (R2 = −0.343, p < 0.001), SCr (R2 = −0.308, p < 0.001), BUN (R2 = −0.361, p < 0.001), UA (R2 = −0.238, p < 0.001), TNFR-1 (R2 = −0.296, p < 0.001), and KIM-1/Cr (R2 = −0.182, p = 0.005). This evidence concerns the gene PNPLA2 and diabetes mellitus.
