  •      CRF (Case report form): A staff member (physician, study nurse), the study-specific data
         transfers per patient in a form. This can happen in paper form or electronically.

    information.
  •      Expression of laboratory data and medical examinations.
  •      Questionnaires can be contributed by study participants as a "self assessment".

    input twice. The subsequent statistical analysis of study results and consider any typos, because
