CLEPAN: an interactive learning platform for clinical epidemiological analysis
CLEPAN is a free, user-friendly platform developed by Aarhus University researchers to help medical and predoctoral students, as well as clinicians, understand the concepts of clinical epidemiology. It offers interactive tools and updated content on epidemiological concepts, study designs, and data visualization, without requiring advanced computer skills.

CLEPAN is a learning platform for clinical epidemiological analysis. It is primarily aimed at medical students, predoctoral students, clinicians without formal research training, and others looking to advance their skills in clinical medicine, epidemiology, and biostatistics. CLPEAN introduces its users to the principles of clinical epidemiology without requiring an advanced computer program.
Key features
There are many ways CLEPAN can assist you with your clinical epidemiological analyses:
- Describe epidemiological study designs and absolute and relative measures of disease occurrence, outcome, and prognosis.
- Provide basic sample size calculation formulas and online calculators for clinical trials and observational studies.
- Explain how to visualize the data prepared for clinical epidemiological studies
- Discuss the types of bias in epidemiology and offer solutions for confounding control via stratification, standardization, and bias analyses.
- And much more.
Updated and improved version available
The updated version of CLEPAN now features data visualization tools, such as histograms, box plots, and pie charts, as well as survival curves and cumulative incidence curves in the presence of competing risks.
The interaction and effect modification analyses are now explained in greater detail, offering users a deeper understanding of their application and interpretation. Finally, recognizing the critical role of bias in epidemiological studies, the updated version places greater emphasis on identifying types of bias and implementing solutions for confounding control (e.g., stratification, direct and indirect standardization, and bias analyses).
