On the estimation of the incidence and prevalence in two-phase longitudinal sampling design.

Abstract

Two-phase sampling design is a common practice in many medical studies. Generally, the first-phase classification is fallible but relatively cheap, while the accurate second phase state-of-the-art medical diagnosis is complex and rather expensive to perform. When constructed efficiently it offers great potential for higher true case detection as well as for higher precision at a limited cost. In this article, we consider epidemiological studies with two-phase sampling design. However, instead of a single two-phase study, we consider a scenario where a series of two-phase studies are done in a longitudinal fashion on a cohort of interest. Another major design issue is non-curable pattern of certain disease (e.g. Dementia, Alzheimer's etc.). Thus often the identified disease positive subjects are removed from the original population under observation, as they require clinical attention, which is quite different from the yet unidentified group. In this article, we motivated our methodology development from two real-life studies. We consider efficient and simultaneous estimation of prevalence as well incidence at multiple time points from a sampling design-based approach. We have explicitly shown the benefit of our developed method...Continue Reading

Alzheimer's Disease: Early Markers

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive and behavioral decline. Targeting markers in the earliest stages of the disease may mitigate the progression of AD. This feed focuses on early diagnosis and markers, as well as environmental, pharmacological, and drug-response biomarkers associated with this disease.

Epidemiology of Aging

This feed focuses on epidemiology of aging and aging-related conditions, including Alzheimer’s disease, dementia, and age-associated cognitive impairment. Here is the latest research.
