Follow up

  • it is important to consider the follow-up rate (the proportion of subjects originally entering the study for whom data are available at the end of the study) when appraising study results
  • the power of the study will be diminished (and the results will be unreliable) if data are available on too few original subjects (e.g. <80%) (1,2)
