The summary table is just what it sounds like: a table that summarizes the key characteristics of the studies you selected.
This is another example of where PICO (D) comes in handy. In this case, your summary table should include the PICO (D) elements of each study.
Your summary table should include information about each study’s:
• Publication year
• Period of enrollment
• Type (e.g., randomized, cohort)
• Summary demographics (mean age, % male/female, race/ethnicity)
• Inclusion/exclusion criteria
• Other PICO(D) elements
