Case series typically involve a much smaller number of patients than the more powerful case-control study or Randomised controlled trial (RCT). In this design patients with a known exposure to a treatment are tracked prospectively to identify new forms of disease or adverse effects. Case series can also be retrospective - here medical records are examined to identify a link between exposure and disease.
