The complex building of current clinical research continues to stand on four methodological pillars - the population surveys, the case-control study, the cohort study and the clinical trial. These four methods, along with their combinations and modifications, enable us to investigate any possible cause-effect relationship across

  1. biological, personal, or social factors or events;
  2. symptoms, diseases, or conditions; and
  3. treatments, procedures, or interventions. 

This 5-day course provides a review of the four methods with emphasis on their complementarities and relative strengths and weaknesses. 

The course will enable the participants to better understand how evidence is constructed in clinical research. Participants will improve their ability to design, conduct, and interpret studies, and write and read scientific papers and grant applications.
