> Berry also pointed out that if the word “common” is used to indicate a 1-10% chance of a nasty side effect (which is recommended usage in the EU for medication leaflets), but a patient thinks that “common” means a 50% chance (which is how many of Berry’s subjects interpreted the word), then the patient might refuse to take the medication because of this misunderstanding. 1-10% chance of a nasty side-effect is high. So yeah, I'd say "common" is appropriate.
