In other words, the researchers do not control the treatments or assign subjects to experimental groups. An observational study is one in which no variables can be manipulated or controlled by the investigator. A prospective, analytical, observational study, based on data, usually primary, from a follow-up period of a group in which some have had, have or will have the exposure of interest, to determine the association between that exposure and an outcome.
