Zero-inflated generalized Poisson models with regression effects on the mean, dispersion and zero-inflation level applied to patent outsourcing rates [PDF]

, 2006
This paper focuses on an extension of zero-inflated generalized Poisson (ZIGP) regression models for count data. We discuss generalized Poisson (GP) models where dispersion is modelled by an additional model parameter.

Determination of Pericardial Adipose Tissue Increases the Prognostic Accuracy of Coronary Artery Calcification for Future Cardiovascular Events [PDF]

, 2012
Objectives: Pericardial adipose tissue (PAT) is associated with coronary artery plaque accumulation and the incidence of coronary heart disease. We evaluated the possible incremental prognostic value of PAT for future cardiovascular events.

What Is the Prognostic Value of a Zero Calcium Score?

Journal of the American College of Cardiology, 2010
Despite remarkable advances in knowledge and technology, heart disease remains the leading cause of death in the U.S. Thus, the search continues for more effective ways to diagnose heart disease early, and hopefully prevent more cardiac deaths. More than 30 years ago, Diamond and Forrester ([1][1])

Long-term follow-up for mortality and cancer in a randomized placebo-controlled trial of vitamin D3 and/or calcium (RECORD Trial) [PDF]

, 2012
Context: Vitamin D or calcium supplementation may have effects on vascular disease and cancer. Objective: Our objective was to investigate whether vitamin D or calcium supplementation affects mortality, vascular disease, and cancer in older people ...

Asymptotic optimality of the quasi-score estimator in a class of linear score estimators [PDF]

, 2006
We prove that the quasi-score estimator in a mean-variance model is optimal in the class of (unbiased) linear score estimators, in the sense that the difference of the asymptotic covariance matrices of the linear score and quasi-score estimator is ...

Intracranial internal carotid artery calcification is not predictive of future cognitive decline

Alzheimer’s Research & Therapy, 2022
Background Intracranial internal carotid artery (ICA) calcification is a common incidental finding in non-contrast head CT. We evaluated the predictive value of ICAC (ICAC) for future risk of cognitive decline and compared the results with conventional ...

Diagnostic accuracy of coronary artery calcium score for excluding obstructive coronary artery disease

Journal of Clinical and Preventive Cardiology, 2022
Background: Studies in western populations have shown that zero coronary artery calcium score (CACS) is associated with a very low prevalence of obstructive coronary artery disease (CAD), even in patients presenting with chest pain.

De-risking primary prevention: role of imaging

Therapeutic Advances in Cardiovascular Disease, 2021
Atherosclerotic cardiovascular disease (ASCVD) is a common disease among the general population, and includes four major areas: (1) coronary heart disease (CHD), manifested by stable angina, unstable angina, myocardial infarction (MI), heart failure, and
