Fig. 1. Overnight 8-hr UGE and UGCR. (A) Distribution of overnight 8-hr UGE values. Outliers of overnight 8-hr UGE above 100,000 mg (N = 2) were excluded in the graph. (B, C) Comparison of the correlation coefficient values between UGCRs and UNCRs.
*P<0.001; †Overnight 8-hr urinary sodium-to-creatinine ratio (UNCR)=overnight 8-hr urinary sodium excretion (mmol/L)/overnight 8-hr urinary creatinine excretion (mg/dL); ‡First-voided morning spot UNCR (M-UNCR)=first-voided morning spot urinary sodium excretion (mmol/L)/first-voided morning spot urinary creatinine excretion (mg/dL).
Abbreviations: UGE, urinary glucose excretion; UGCR, urinary glucose-to-creatinine ratio; M-UGCR, first-voided morning spot UGCR; NGT, normal glucose tolerance; T2DM, type 2 diabetes mellitus.
