UPLC/Q-TOF MS-based OPLS-DA in the urine specimens collected from injury and control groups under positive and negative modes. (a, b) Score plots of the 1 d group were obtained by the UPLC/Q-TOF MS-based analyses under positive and negative modes. (c, d) Score plots of the 3 d group were obtained by the UPLC/Q-TOF MS-based analyses through positive and negative modes.
