title: [Correlation measures in epidemiology].
abstract: When a significant correlation has been noted between the occurrence of a disease and exposure to a risk factor, it becomes necessary to measure the strength of the correlation. This can be done using either relative risk or odds ratio techniques depending on the type of study. The purpose of article this article is to present guidelines for calculation and interpretation of these indicators using examples taken from the Médecine Tropicale journal.
