In a systematic literature review, it's important to describe the selection of articles that make up the outcome.The selection criteria, including inclusion and exclusion criteria, are predetermined and based on the well-defined research question. It is crucial for these criteria to be clearly defined and documented to ensure transparency and reproducibility throughout the review process.
Your inclusion criteria help you determine which articles to include and could be factors such as:
Your exclusion criteria help you determine which articles to exclude and could be factors such as:

From a large number of articles extracted from the comprehensive searches, you will retain a smaller subset that matches the purpose of your research question and the associated inclusion criteria.
Various checklists are available to aid in the quality assessment of articles. These checklists provide structured criteria to evaluate the reliability and validity of research studies. By utilizing such tools, researchers can ensure thorough and consistent appraisal of study quality, enhancing the credibility of their findings.
Differences in research design usually requires different checklists for qualitative and quantitative studies. Separate checklists have also been developed to assess the specific subcategories within each research approach.
