Inclusivity helps to identify and make use of the full range of relevant evidence types, sources and expertise.
These guidelines catalogue four types of evidence of pathogenicity and recommend rules for combining these evidence types to diagnose the likely clinical significance of sequence variants.
The method enables a diverse range of evidence types to be synthesized in order to examine potential relationships between a public health environment and outcomes.
Based on an analysis of 54 empirical investigations of social learning and natural resources published after peer review, we investigated aspects of research design that include data collection methods, evidence types and the researcher's role.
Statements about the presence of the other evidence types are defined similarly.
Given the mix of study designs and evidence types, it was not possible to organise the literature according to intervention type or theoretical position.
This led to significant debates about the role of Bayesian approaches in presenting evidence types that do not have an established statistical base akin to DNA and more generally, how forensic evidence should be presented in court (Berger et al. 2011; Hamer 2012; Morrison 2012; Redmayne et al. 2011; Robertson et al. 2011).
While systematic review methods were initially developed for the purpose of synthesising randomised controlled trials, a growing interest in such reviews in the social sciences has led to the development of methods for synthesising a range of evidence types, including qualitative evidence, commentaries and expert opinion (Joanna Briggs Institute 2014; Oliver 2015).
Scoping reviews can also incorporate a range of evidence types, but differ from a systematic review in that the evidence is summarised to provide an overview, or map, of the available evidence, rather than a set of synthesised findings (Arksey and O'Malley 2005).
One review combined both evidence types.
Both of the reviews that reported inconsistency investigated differences and did not combine evidence types.
