3
Q
Randomized Controlled Trial
A
- Two groups, experimental and control
- Experimental group receives the intervention
- Control group receives a placebo
- Double-blind – gold standard, neither the patient nor the physician knows which group the patient is in
- Drug trials (Phase III) = RCT
4
Q
Cohort study
A
- group with a given exposure/risk factor vs. group without that exposure
- Does exposure increase likelihood of disease
- Takes place over period of time
- Method of identifying risk factors for diseas
- Prospective or Retrospective
- Measures Relative Risk
5
Q
Case Control Study
A
- Group with disease vs. group without
- Looks for prior exposure or risk factors
- Measures odds ratio
6
Q
Cross Sectional Study
A
- Group of people at one specific time
- Looks at frequency of disease and related risk factors
- Measures disease prevalence
