in observational studies, whether there is exposure is determined by the subject himself/herself or naturally. Note: The difference between a trial and a study is quite fuzzy, but they can be distinguished as follows: a trial bears on an intervention that will change the course of things and that applies to humans, while a study examines the outcomes of an intervention or of exposure to a given factor, or may have other aims, such as observing the course of a disease. A trial may be part of a study, but the reverse is not true.»
