Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. They determine the limits for the evidence synthesis and are typically reported in the methods section of the publication. For example, patients with liver disease would be excluded if coagulation parameters would impact the outcome. These criteria are usually applied to the results of a search and are not used to limit the search results. Cluster sampling also involves dividing the population into subgroups, but each subgroup should have similar characteristics to the whole sample. Scribbr.
