PLS-DA score plots of different groups based on plasma spectral data of UPLC-QTOF-MS positive ion mode. One point stands for one subject. (A) PLS-DA score plot of the NGR vs pre-DM vs DM groups. (B) PLS-DA score plot of the NGR vs DM groups. (C) PLS-DA score plot of the NGR vs Pre-DM groups. (D) PLS-DA score plot of the pre-DM vs DM groups.
