    Time frame: Week 0,1,4,7,12,13,15

    The total time spent napping per week as a percent of the total time asleep for subjects who napped during the baseline period. Mean values reported: baseline(week 0), double-blind phase(weeks 1,4,7,12), single-blind follow-up(week 13), non-drug treatment follow-up(week 15) & average for double-blind phase(average of weeks 1,4,7,12 values).

  60. Mean Change From Baseline in Insomnia Severity Index Total Score Averaged Over the 12 Week Double Blind Study Period

    Time frame: Baseline (week 0), Day 1 (post first dose) - week 12

    Change from baseline in the Insomnia Severity Index Total Score which ranges from 0-28. Lower scores represent better sleep. The change is calculated as the average over the double blind period (average of post-dose values from weeks 3,6,9,12) minus the baseline value.

  61. Mean Change From Baseline in Insomnia Severity Index Total Score at Various Study Time Points

    Time frame: Baseline (week 0), Weeks 3,6,9,12,14,16

    Change from baseline in the Insomnia Severity Index Total Score which ranges from 0-28. Lower scores represent better sleep. The change is calculated as time point value minus the baseline value.

  62. Mean Insomnia Severity Index Total Scores at Various Study Time Points

    Time frame: Weeks 0,3,6,9,12,14,16

    The Insomnia Severity Index Total Score ranges from 0-28. Lower scores represent better sleep. Mean values are reported at baseline(week 0), double-blind phase(weeks 3,6,9,12), single-blind follow-up(week 14), non-drug treatment follow-up(week 16), and the average for the double-blind phase(average of weeks 3,6,9,12 values).

  63. Mean Change From Baseline in Physical Component Summary of the Short Form-36 Scale

    Time frame: Baseline (week 0), Weeks 6, 12, 16

    Physical component summary of Short Form-36 Scale measures subject's perception of their physical health, where the normal mean for general US population is 50.Scores above/below 50 represent better than/worse than the general US population. Higher scores represent better outcomes. Change is calculated as time point value minus baseline value.

  64. Mean Physical Component Summary of the Short Form-36 Scale Scores.

    Time frame: Weeks 0,6,12,16

    This scale measures subject's perception of their physical health, where the normal mean for general US population is 50.Scores above/below 50 represent better/worse than general US population. Change calculated as time point value minus baseline value: baseline(week0), double-blind (weeks 6,12)and non-drug treatment follow-up(week16).

  65. Mean Change From Baseline in Mental Component Summary of the Short Form-36 Scale Scores

    Time frame: Baseline (week 0), Weeks 6,12,16

    Mental component summary of Short Form-36 Scale measures subject's perception of their physical health, where the normal mean for general US population is 50. Scores above/below 50 represent better than/worse than the general US population. Higher scores represent better outcomes. Change is calculated as time point value minus baseline value.

  66. Mean Mental Component Summary of the Short Form-36 Scale Scores

    Time frame: Weeks 0,6,12,16

    This scale measures subject's perception of their physical health, where normal mean for general US population is 50. Scores above/below 50 represent better/worse than general US population. Change calculated: time point value minus baseline value. Mean values: baseline(week0), double-blind phase(weeks 6,12)& non-drug treatment follow-up(week 16).

  67. Mean Change From Baseline in the Sheehan Disability Scale Total Score.

    Time frame: Baseline (week 0), Weeks 6,12,14,16

    Sheehan Disability Scale Total Score (range 0-30)measures subject's level of disability & includes: work/school, social life, family life/home responsibilities, days lost &days underproductive; higher scores represent higher degree of disability/impairment. Change is calculated as time point value minus baseline value.

  68. Mean Sheehan Disability Total Scores

    Time frame: Weeks 0,6,12,14,16

    Sheehan Disability Scale Total Score (range 0-30) measures subject's level of disability; includes work/school, social life, family life/home responsibilities, days lost, days underproductive; higher scores represent higher degree of disability/impairment.
