Multiple logistic regression analysis using PN as a dependent variable among the NGT, IGR and DM subjects.

NGT, normal glucose tolerance; IGR, impaired glucose regulation; DM, diabetes mellitus; FPG, fasting plasma glucose; 2hPG,2-h postprandial plasma glucose; HbA1c, glycated hemoglobin A1c; HDL, high density lipoprotein; LDL, low-density lipoprotein; eGFR, estimated glomerular filtration rate; ACR, albumin-to-creatinine ratio;The OR corresponds to a 1 unit change in categorical factors associated with PN;N/A: not applicable.*2hPG levels were from OGTT (NGT, IGR and newly-diagnosed diabetes subjects), and 100g steamed bread meal test (Known diabetes subjects), so these data could not be combined in the regression analysis in total subjects.
