In medical studies, treatments are tested within a group of study participants. To determine if a new treatment works, various outcomes are measured in the people who take part in the study. You will be given a sentence of a study report in which your task is to list the phrases that give information about the outcomes of the study.

 outcomes regarding the intervention: like effectiveness, costs
 the score on a medical test or questionnaire,
 positive or negative events in the patient groups: like quitting smoking, or adverse reactions.
 Do not mention numbers or results, interpretations of outcomes, outcome mentions without relevant information.
