They determine the limits for the evidence synthesis and are typically reported in the methods section of the publication. It allows you draw more precise conclusions by ensuring that every subgroup is properly represented in the sample. If it is practically possible, you might include every individual from each sampled cluster. In a non-probability sample, individuals are selected based on non-random criteria, and not every individual has a chance of being included.

The exclusion criteria include factors or characteristics that make the recruited population ineligible for the study. The most straightforward way to include or exclude results is to use database limiters (filters), usually found on the left side of the search results page. This included defining the research question, followed by confirming inclusion and exclusion criteria, search of the literature, selection of research studies based on the inclusion and exclusion criteria, the extraction of information or data from the selected studies, evaluation of risk of bias in the research, presentation of results and .
