Systematic reviews are the best way to understand the effects of treatments because they consider all the relevant, reliable evidence.

This resource will be useful for teachers, lecturers or others who want to explain systematic reviews using clear and informative visuals.

    Minor comment. The slides are great to show us how the forest plots work and the example of steroids and deaths exemplify well. However, towards the end it is unclear what the message is. Slide 8, for example (a repeat of the plot without any explanations) is cryptic. The final slide seems to say that over a decade there was sufficient evidence demonstrating the positive effect of steroids (which ends in the 80s, i.e., 30 years ago!), and another loose comment about whether another decade and 10 trials are needed to convince clinicians to change practice…Remember it’s a PowerPoint presentation, so normally one elaborates over the slide. I think the take-home message would be more powerful if the author would add a few more explicit conclusions to the slide. Thanks.

      I think these are great suggestions, Alfredo. Our purpose in putting the slides up for now was to provide a resource that people could use in their own teaching as well as to inform themselves. But you are absolutely right, having the speakers’ notes and/or a voiceover would be ideal.

      Hi Alfredo.

      Just to let you know that Steve has very kindly recorded a voice-over of the presentation and I have added it to the post above.

      Hopefully this addresses your question. Please let us know if it doesn’t!

      cheers
