For each research study in your systematic review, you’ll need quantitative information that paints a clear picture of the people who participated in the research.

Here’s some of the data you should gather about the research participants in each study:

  • Age range and average age
  • Number of males versus females
  • Other demographic information: country of origin, educational level, economic background, etc
  • How was each participant’s disease or condition defined/diagnosed?
  • How severe was each participant’s disease/condition?
  • Did participants have any other related diseases or health issues?
  • Is there any other baseline data about the participant’s health before the - intervention took place?
  • Where did the participants receive the intervention/comparator?
  • How long did each person participate in the study?
