What researchers measure

Primary outcomes

  1. Percentage of Participants With Response of Very Convenient or Somewhat Convenient

    Participant reported outcome questionnaire was the assessment of participant's convenience with drug treatment based on following categories: very convenient or somewhat convenient and not convenient or not at all convenient. Value of 1 was reported if participant answered 'very convenient' or 'somewhat convenient' and 0 if participant answered 'not convenient' or 'not at all convenient'.

    Time frame: Days 11-12

Secondary outcomes

  1. Percent Compliance With the Prescribed Treatment Regimen

    Percent compliance with the prescribed treatment regimen was calculated as 100 multiplied by (number of tablets taken by the participant divided by number of tablets prescribed).

    Time frame: Days 11-12

  2. Percentage of Participants Who Were 100 Percent Compliant With Prescribed Treatment Regimen

    Percent compliance with the prescribed treatment regimen was calculated as 100 multiplied by (number of tablets taken by the participant divided by number of tablets prescribed). Value of 1 was reported if percent compliance equals to 100, and 0 if percent compliance was non-missing and less than 100.

    Time frame: Days 11-12
