Introduction to study designs - intervention studies and randomised controlled trials Learning objectives: You will learn about interventional study design and its strengths and weaknesses. Interventional studies are often performed in laboratories and clinical studies to establish beneficial effects of drugs or procedures. The present section introduces the readers to randomised controlled study design.

The difference between an observational study and an experiment is that A . in an observational study, only one group is studied, and in an experiment, two groups are studied. B . in an observational study, the researchers do not control treatment, and in an experiment, they do. C . in an experiment, cause-and-effect is analyzed, and in an observational study, it is not. D . in an experiment, one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time.

Study Designs A non-analytic or descriptive study does not try to quantify the relationship but tries to give us a picture of what is happening in a population, e.g., the prevalence, incidence, or experience of a group.hey may sometimes also include analytic work (comparing factors “” see below). An analytic study attempts to quantify the relationship between two factors, that is, the effect of an intervention (I) or exposure (E) on an outcome (O).

Interventional cardiology Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter. A large number of procedures can be performed on the heart by catheterization.

Statistics - Observational Studies versus Designed Experiments (Section 1.2) (An observational study measures the value of response variable without attempting to influence any of the response or explanatory variables of the individual). That is, in an observational study, the researcher observes the behavior of the individuals in the study without trying to influence the outcome of the study.

Radiology Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually carried out by the radiographer, often known as a radiologic technologist.Depending on location, the diagnostic radiologist, or reporting radiographer, then interprets or reads the images and produces a report of their findings and impression or diagnosis.he acquisition of medical imaging is usually carried out by the radiographer, often known as a radiologic technologist.

Observational Research Cases studies and archival research are special types of observational research. Naturalistic (or nonparticipant) observation has no intervention by a researcher. It is simply studying behaviors that occur naturally in natural contexts, unlike the artificial environment of a controlled laboratory setting.

Difference Between Observational Study and Experiments Observational Study vs Experiments. Observational study and experiments are the two major types of study involved in research. The main difference between these two types of study is in the way the observation is done. In experiments, the researcher will undertake some experiment and not just make observations.
