Evidence

  • Evidence in its broadest sense includes everything that is used to determine or demonstrate the answers to our clinical questions.
  • Evidence based stroke care aims to apply the best available evidence gained from high quality research to help us make clinical decisions about stroke care.
  • One small study, even if well-designed, may not provide enough evidence to support a clinical decision.
  • A body of evidence can be built up from a number of research studies which have all answered the same question.
  • Often the results of similar studies are viewed together within a systematic review.
