Real world trials generally don't use placebos. Instead, the control is the best treatment currently available. After all, you're usually not interested in whether some drug works better than sugar, but whether it's worth using it instead of or in addition to some currently available treatment. So the control group get the best treatment they could have got if they were not in the study, while the experimental group may or may not fare better.
