Outcome Measures

Primary Outcomes (14)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    Baseline (fasting state before breakfast at 7:30AM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    4 Hours (immediately before lunch at 11:30AM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    5.5 hours (after lunch at 13:00PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    6.5 hours (after lunch at 14:00 PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    7.5 hours (after lunch at 15:00PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    8.5 hours (after lunch at 16:00PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    9.5 hours (after lunch at 17:00PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    10.5 hours (after lunch at 18:00PM)

  • Intensities of multiple serum metabolites

    The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    11.5 hours (after lunch at 19:00PM)

  • Intensities of multiple urinary metabolites

    The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    Baseline (overnight urine sample collected at 7:30AM)

  • Intensities of multiple urinary metabolites

    The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    3.5~4 hours (before lunch urine sample collected during 11:00~11:30AM)

  • Intensities of multiple urinary metabolites

    The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    4.5~6.5 hours (2-hour after lunch urine sample collected from 12:00 to 14:00PM)

  • Intensities of multiple urinary metabolites

    The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    6.5~8.5 hours (4-hour after lunch urine sample collected from 14:00 to 16:00PM)

  • Intensities of multiple urinary metabolites

    The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.

    8.5~11.5 hours (7-hour after lunch urine sample collected from 16:00 to 19:00PM)
