Background: Cochrane systematic reviews (SR) focus on randomized clinical trials (RCT) but some Cochrane Review Groups (CRG) also consider non-randomized studies (NRS) as eligible. However, NRS cover designs defined with different labels not consistently applied among researchers.

This learning activity aims to introduce you to some common study designs. It is made up of some learning and some testing of that learning, using title-abstract records. It covers the main interventional and observational study designs. We estimate this module will take around one hour to complete. Cohort studies: prospective and retrospective designs. A well-designed cohort study can provide powerful results.

For example, Cochrane Effective Practice and Organisation of Care accepts protocols that include interrupted time series (ITS) and controlled before-and-after (CBA) studies, and specifies some minimum criteria for these types of studies. These study designs all have similar components (as we’d expect from the PICO): A defined population (P) from which groups of subjects are studied; Outcomes (O) that are measured; And for experimental and analytic observational studies: Interventions (I) or exposures (E) that are applied to different groups of subjects; Overview of the design tree Introduction to Study Design.

include data from different study designs that are not suitable for lumping all together in analysis; or may have captured a very wide range of interventions. Therefore, other ways of expressing and synthesising the results of studies collected together for review are needed.

Because Cochrane reviews address questions about the effects of health care, they focus primarily on randomized trials. include a broader range of study designs in EPOC reviews. Consideration should generally be given to four types of study designs: Randomised trials Non-randomised trials Controlled before-after studies Interrupted time series studies and repeated measures studies 2012-03-01 are provided in Appendix A. Appendices to the accompanying Study Design Guide contain glossaries of useful terms for study design and the characterisation of study design. These are adapted primarily from the Cochrane Glossary, with additional material from other sources.

Search strategies that include a methodological filter focusing on study design of observational studies might be useful for improving the precision of the search performance. Objectives: To assess the sensitivity and precision of a search strategy with a methodological filter to identify observational studies in MEDLINE and Embase.
