Definitions:

Incidence Rate

The rate at which new cases of a condition, disease, or event occur in a population over a specified period.

Asbestos Exposure

The inhalation or ingestion of asbestos fibers, which can lead to serious health conditions like mesothelioma or lung cancer.

Multiplicative Scale

A measurement scale where units are exponentially related, often used in contexts where growth or change occurs at constant rates.

Effect Measure Modifier
