Outcome Measures

Primary Outcomes (2)

  • Quality of life score

    The short-form (SF)-36 Questionnaire generates scores in the categories: physical function, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, and general health. Scores up to maximum 100, with higher scores representing better quality of life

    At enrollment

  • Immune Status

    Immune Status Questionnaire (ISQ) to define a measure of perceived immune status, consists of seven representative immune-associated symptoms and diseases. The Immune Status Questionnaire scores respondents out of 10, with 10 being a better outcome and lower scores worse outcome.
