1. Describe if each of the sources according to the category (e.g. primary research studies, systematic reviews, and/or practice guidelines) met the majority of criteria from the Critical Appraisal Tools. If they do not meet the majority of the criteria, did you decide to omit any sources when formulating your conclusions and recommendations? If so, indicate which ones and rationale for their exclusion.
2. Describe if there are similar variables and outcomes in all the sources. Are the results from each source significant (statistically and clinically)? Were the results of the studies and reviews similar or different.
3. Discuss if conclusions and recommendations for practice are consistent among the 3 types of sources of evidence (primary/original research, systematic reviews, and clinical practice guidelines). Summarize the recommendations for practice (specific to your PICO question: For adults over 50 years, does the use of fish oil supplements and/or omega-3 fatty acids reduce the future risk of cardiovascular disease compared with adults over 50 years who do not take these supplements. ) among all of your evidence and if they are consistent among the sources?
