  • Prospective design
  • to assess the efficacy of an intervention or treatment
  • comparison with a control group/treatment

The outcome of a trial can be ...

When can a cross-over study only be used?

  • If the exposure has no long lasting effect
  • for outcomes that are reversible and that can change within a short time period
  • treatments may be separated by a 'wash-out' period
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding
