Question 6

Question
A new agent to control psoriasis is being compared to placebo in a randomized trial.

Question 7

Question
A new anti-rheumatic medication showed great promise in early trials, so local physicians became interested in studying its benefits in a clinical trial.

After obtaining consent, patients attending outlying clinics will receive usual treatments, while patients attending the central clinic will receive the new medication. Patients will be followed for one year, with regular assessment of serum markers of inflammation, involvement by physical exam, and symptoms scores on a validated instrument.

Answer
  • composite outcome
