Natural History Study

A natural history study is a preplanned intended to track the course of the disease. Its purpose is to identify demographic, genetic, environmental, and other variables (e.g., treatment modalities, concomitant medications) that correlate with the disease’s development and outcomes. Natural history studies are likely to include patients receiving the current standard of care and/or emergent care, which may alter some manifestations of the disease.

K-anonymity

A privacy principle that ensures that data can be released without revealing the identity of the individuals from whom it was collected. In a dataset that is k-anonymous, any individual's data cannot be distinguished from at least k-1 other individuals' data.
