  1. *Based on t-tests comparing means of the two groups.
  2. In Study 3, sample size was smaller for health states representing sexual dysfunction and increased prolactin because each participant rated only the gender-specific health state.
  3. HS = Health state.
  4. ADHD = Attention deficit/hyperactivity disorder.
