Global urinary metabolic profiling of the osteonecrosis of the femoral head based on UPLC-QTOF/MS.INTRODUCTION
 Ultra-performance liquid chromatography-quadrupole time of flight tandem mass spectrometry (UPLC-QTOF/MS) in combination with multivariate statistical analysis was developed and performed to identify the global urinary metabolic profiling of ONFH.
