  1. * A lower ICQ score is closer to optimal behavior
  2. Study end: day 60 (study completion) or early study discontinuation at any time point
  3. Comparisons at time-points between study groups for ICQ subscale were not statistically significant, P > 0.05.
  4. §Least square means ± SE
  5. a score at enrollment vs. day 60, P = 0.001
  6. b score at enrollment vs. day 60, P < 0.001
