Definition of Studies
| Study | Defintion |

| Cohort | A study that involves the identification of a group of individuals with specific characteristics in common and follows them over time to gather data about exposure to factors and the development of the outcome of interest. |
| Cross-sectional | A study where exposure factors and outcomes are observed or measured at one point in time in a sample from the population of interest, usually by survey or interview. |
| Meta-analysis | A systematic, quantitative method that combines the results of all relevant studies to produce an overall estimate. A meta-analysis can be part of a systematic review, but not all systematic review include meta-analysis. |
| Observational | An observational study is used to answer a research question based purely on what the researcher observes. There is no interference or manipulation of the research subjects, and no control or treatment groups. |
| Randomized controlled trial | Individuals meeting eligibility requirements are randomly assigned into an experimental group or a control group. The experimental intervention and its alternatives are clearly defined and their implementation is closely managed by the researcher. |
| Umbrella review | An umbrella review compiles evidence from multiple existing systematic reviews and is one of the highest levels of evidence. Allowing easy comparison between other individual reviews, the umbrella review may address a broader question and can be useful for comparing interventions. |
