Look out for treatment effects that are described just using words, or use more emotive vocabulary.
A treatment effect is a change in an outcome caused by a treatment. The size of a treatment effect can be described using numbers. For example, 6 out of 10 children may have no feeding difficulties following a tongue tie resection and 5 out of 10 children may have no feeding difficulties without that treatment. Then the effect of the treatment (the difference) is 1 more person out of 10 who will be better with the treatment.
Words can also be used to describe treatment effects. For example 2 more people out of 10 might be described as a “small effect”. Words can be easier to understand than numbers, but they can mean different things to different people. Also, words can be used to trick people. For example, someone selling a treatment might say that it has “amazing results” or might describe a treatment as “natural”, suggesting that it is safe because of that.
