Baseline risk refers to the probability of an event occurring in a group of people who are not exposed to any additional risk factors or interventions. It serves as a reference point for evaluating the effect of interventions and understanding absolute and relative risk changes in clinical and epidemiological studies.

Baseline Risk

Baseline risk

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. It is a fundamental concept in statistics and mathematics, providing a quantitative description of the expected frequency of outcomes in a random experiment.

Interventions are strategic actions designed to improve outcomes, modify behaviors, or address specific issues within a given context. They are employed across various fields, including healthcare, education, and social services, to effectively address and mitigate problems or challenges.

interventions

A reference point is a basis or standard for evaluation, comparison, or understanding of something, often serving as a benchmark or anchor in various fields such as physics, psychology, and economics. It is crucial for establishing context, measuring change, and making informed decisions by providing a stable framework against which other variables or phenomena can be assessed.

Clinical Studies

Epidemiological studies are essential for understanding the distribution and determinants of health-related states or events in specific populations, and they provide the foundation for public health interventions and policy-making. These studies are typically categorized into descriptive, analytical, and experimental designs, each serving distinct purposes in investigating disease patterns and causes.
