It's important that you are familiar with how you expect or can expect your question to be answered within the literature. During the E phase of the PET process, you must not only find relevant literature, but also appraise each resource for its relevancy and applicability to your environment. Once you have successfully created a search strategy, searched bibliographic databases, and located relevant literature resources, it is important that you and your team are comfortable with the types of evidence, as well as the types of publications you will be appraising. Additionally, because appraisal standards for various publication types differ from one another, understanding what kind of evidence your question is seeking is essential to being prepared for the appraisal and Translation stages of the EBP process.

|Definition||Types of Publications||Where?|
|Translational Literature||Research findings that have been translated into guidelines used in the clinical setting.||
|Evidence Summaries||Summaries of the literature to summarize results of the studies.||
|Primary Evidence||Data collected directly from patient or subject contact||
For each applicable PICO part that's used in the PICO question, list searchable keywords to identify each topic.
After searching the database using the strategies above, take note of the first few results as well as how many total results the strategy returned. If patient age is essential to the analysis of the literature, filter results to reflect that. Next, refer to your question type, evidence types and publication types and filter your results to show only those publication types you and your team decided on. Use the 6S pyramid shown to the right to help you distinguish between the levels of evidence and the types of studies included in each pyramid level
