SYSTEMATIC REVIEWS
We have given priority to a research method called the systematic review. in preparing a systematic review the researcher
- asks a clear question eg what is the effect of lifting weights on the strength of older people?
- finds all the randomised controlled trials designed to answer this questions
- reviews all the trials and classifies them as with of good enough quality to use or of inadequate quality
- combines the results of all the good quality trials
- publishes the results including references to the trials deemed inadequate
