You will be given a sentence of a study report in which your task is to list the phrases that describe the intervention(s) of the study.

Interventions are: a specific drug, surgery, talking therapy, a lifestyle modification, control or placebo treatment. Do not include details, dosages, frequency and duration, intervention mentions that are not in an informative span of text.
