Key Concepts

Event Identification

In studies analyzing associations, clearly defining the events of interest is crucial. This involves identifying two distinct outcomes or conditions whose relationship is being studied. In epidemiological research, one event is often a risk factor or exposure (like a health condition or behavior), and the other is an outcome (such as another health condition), which together can help determine if there is any association between them.

Independent vs Dependent Events

In probability and statistics, events are independent if the occurrence of one does not affect the likelihood of the occurrence of the other. They are dependent if the occurrence of one event changes the probability of the other event happening. In epidemiological studies, discovering an increased risk of the outcome in the presence of the risk factor indicates that the events are dependent, meaning that there is an association between the two conditions.

Conditional Probability

Conditional probability is a key concept used to measure the probability of one event occurring given that another event has occurred. It helps in assessing whether the events in a study are independent or dependent. If the probability of the outcome given the exposure is different from the unconditional probability of the outcome, it suggests that the events are dependent on one another.
