Think about an illness that you might get. Imagine someone claiming (saying) that a particular treatment might help you get better. | ||||||
---|---|---|---|---|---|---|
 | How likely are you to find out what the claim was based on (e.g., by asking the person making the claim)? | How likely are you to find out if the claim was based on a research study comparing the treatment with no treatment (a fair comparison)? | How likely are you to say ‘yes’ if you are asked to participate in a research study comparing two treatments for your illness (a fair comparison)? | |||
