The study designs can be broadly classified as experimental or observational based on the approach used to assess whether exposure and an outcome are associated. In an experimental study design, researchers assign patients to intervention and control/comparison groups in an attempt to isolate the effects of the intervention.
2018-02-09 · Analytic epidemiology incorporates a comparison group in its study designs. Experimental studies involve laboratory experimentation in in vitro conditions and in in vivo conditions. In this type of studies, a laboratory trial is carried out based on a hypothesis decided by the epidemiologist. Introduction to epidemiology: Week 8 class exercises on analytic epidemiology to practice assessing the study design used in different examples.

In conclusion, this article presents a brief overview of the various single study designs in clinical epidemiology with particular reference to sexual health research. Evidence from different studies addressing the same research question can be synthesised in a systematic way to provide more evidence than can be gained from individual studies (systematic overview or meta-analysis). Experimental Study Designs: Randomised clinical trials; Experimental Study Designs: Other non-randomised interventional studies; Observational Study Designs: Introduction; Observational Study Designs: Cross-sectional study; Observational Study Designs: Case control study; Observational Study Designs: Cohort study; Observational Study Designs: Ecological study The study designs can be broadly classified as experimental or observational based on the approach used to assess whether exposure and an outcome are associated.
