What it means

A sham is the procedure equivalent of a placebo. The participant goes through the motions of the procedure, but the part expected to have an effect is not performed.

Why it matters if you take part

Shams are used where the treatment is a device or a procedure rather than a medicine. As with a placebo, the consent process explains what the sham involves before you agree.
