Making sense of the evidence with randomized controlled trials
Posted on 4th February 2013 by Jamie Loan
This is a PDF file of a PowerPoint presentation that emphasises the importance of randomizedÂ controlled trials (RCTs) and subsequent meta-analysis in evidence-based medicine. It gives four real-life examples of situations where equipoise in clinical decision-making has demanded an RCT and the outcome has influenced practice. It then briefly explains the importance ofÂ randomizationÂ and allocation concealment.

I gave this a low score because of the limited utility of this resource. A PowerPoint without the accompanying oral presentation does not make lots of sense and important detail is missed out. Further, this is quite a basic resource aimed at laypeople and so is perhaps â€œpreaching to the convertedâ€ when read by users of this website.
However, it may well be of use if you have to prepare a presentation for a group of laypeople/beginners by providing entertaining examples.
