Warranty Period of a Calcium Score of Zero [PDF]
JACC: Cardiovascular Imaging, 2021 This study sought to quantify and model conversion of a normal coronary artery calcium (CAC) scan to an abnormal CAC scan.Although the absence of CAC is associated with excellent prognosis, progression to CAC >0 confers increased risk. The time interval for repeated scanning remains poorly defined.This study included 3,116 participants from the MESA ...

Testing for zero-modification in count regression models [PDF]
, 2006 Count data often exhibit overdispersion and/or require an adjustment for zero outcomes with respect to a Poisson model. Zero-modified Poisson (ZMP) and zero-modified generalized Poisson (ZMGP) regression models are useful classes of models for such ...

How Low-Risk Is a Coronary Calcium Score of Zero? [PDF]
Circulation, 2008 Coronary artery calcium (CAC) scoring by computed tomography (CT) has been the subject of intense interest and critical scrutiny since it was first reported as a clinical tool in 1990.1 With improvements in study design, greater availability of coronary CT scanners, and increased attention to the posttest prognosis of patient samples and asymptomatic ...

Optimality of Quasi-Score in the multivariate mean-variance model with an application to the zero-inflated Poisson model with measurement errors [PDF]
, 2006 In a multivariate mean-variance model, the class of linear score (LS) estimators based on an unbiased linear estimating function is introduced. A special member of this class is the (extended) quasi-score (QS) estimator.

Prospective Study on Clinical Outcome of Coronary CT Angiography in Patients with Suspected Coronary Artery Disease: Three-year Follow-up Study [PDF]
International Journal of Anatomy Radiology and Surgery, 2020 Introduction: Coronary Artery Disease (CAD) is one of the leading causes of morbidity and mortality in India. Coronary Computed Tomography Angiogram (CTA) is a non-invasive imaging modality for evaluation of CAD and has high accuracy in ruling out ...

Association of Coronary Artery Disease Assessed by CT-calcium Score with Left Ventricular Diastolic Dysfunction [PDF]
Al-Azhar International Medical Journal, 2023 Background: Atherosclerotic vascular disease starts early and progresses silently for decades. Non-obstructive atherosclerotic plaques promote functional changes in vascular tone like (diastolic dysfunction) due to vasoactive mediator release and ...
