Meta-analysis is the statistical process of combining the results from several studies that is often part of a systematic review. RCTs are by definition prospective. Verbatim quotes of participants can be used to illustrate these themes. Irrespective, both groups are then followed, often over long periods of time.

At the end of the period of observation the incidence of disease or frequency of health outcome in the exposed group is compared to that in the unexposed group.

Each arm of the study is then followed up and the amount or severity of the disease measured in the intervention group and compared with the control group. This is what is meant by a systematic review. An RCT is a type of interventional or experimental study design.

What is a Cohort study? Alternatively exposed and unexposed populations may be chosen separately. Participants individuals or groups are randomly allocated to receive either the new intervention being tested or a control treatment usually the standard treatment or a placebo.

You then determine the proportion of cases who were exposed to any risk factor of interest in the past, and compare this with the proportion exposed in the control group. The study is generally prospective as it looks forward from potential cause to consequence.

These are the cases. Controls without the health outcome are then chosen. What is a Case-Control study? A case-control study belongs to the observational group of studies.

A qualitative study examines the experiences and beliefs of people from their own perspective.

What is a Systematic Review? In this study a population who do not have the health outcome or disease of interest are first divided into those who are exposed to a risk factor and those who are not.

Frequently there will have been more than one study addressing a particular health question. The study is generally retrospective because it looks backwards in time to the earlier exposures of individuals.

It can take many forms including in-depth interviews and focus-groups with analysis attempting to identify underlying themes. A cohort study, also known as a follow-up or longitudinal study, is another observational study design.

The most obvious sign that a review is systematic will be the presence of a methods section. It begins by choosing individuals who have a health outcome or disease whose cause you want to investigate.
