PURPOSE To review the literature on the diagnostic performance of multidetector computed tomographic (CT) angiography for assessment of symptomatic coronary artery disease, with conventional coronary angiography as the reference standard. MATERIALS AND METHODS A PubMed and manual search of the literature published between January 1998 and May 2006 on use(More)
Meta-analysis of receiver operating characteristic (ROC)-curve data is often done with fixed-effects models, which suffer many shortcomings. Some random-effects models have been proposed to execute a meta-analysis of ROC-curve data, but these models are not often used in practice. Straightforward modeling techniques for multivariate random-effects(More)
The aim of the study was to compare the diagnostic performance of endoscopic ultrasonography (EUS), computed tomography (CT), and 18F-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in staging of oesophageal cancer. PubMed was searched to identify English-language articles published before January 2006 and reporting on diagnostic performance(More)
OBJECTIVES The Medical Outcomes Study Short Form 36-Item Health Survey (SF-36) is the most widely used generic instrument to estimate quality of life of patients on renal replacement therapy. Purpose of this study was to summarize and compare the published literature on quality of life of hemodialysis (HD), peritoneal dialysis (PD), and renal transplant(More)
PURPOSE To determine the optimal width and timing of the electrocardiographic (ECG) pulsing window within the cardiac cycle in relation to heart rate (HR), image quality, and radiation exposure in patients who are suspected of having coronary artery disease. MATERIALS AND METHODS The institutional review board approved the study, and all patients gave(More)
PURPOSE To obtain the best available estimates of the diagnostic performance of multidetector computed tomographic (CT) angiography compared with that of digital subtraction angiography (DSA) in the assessment of symptomatic lower extremity arterial disease and to identify the most important sources of variation in diagnostic performance between studies.

BACKGROUND Many studies have been published on the diagnostic performance of noninvasive tests for the assessment of coronary artery disease. The objective of the present study was to compare the published literature on the diagnostic performance of stress echocardiography, stress single-photon-emission computed tomography (SPECT), and electron beam(More)
OBJECTIVE To assess the relationship of coping style with depression, burden and life satisfaction in caregivers of patients with subarachnoid haemorrhage. DESIGN Cross-sectional study. PARTICIPANTS Forty-one primary caregivers of patients with subarachnoid haemorrhage. METHODS Caregivers completed several questionnaires within the first year after(More)
OBJECTIVES To evaluate the time course of health-related quality of life (HRQoL) after moderate to severe traumatic brain injury (TBI) and to identify its predictors. DESIGN Prospective cohort study with follow-up measurements at 3, 6, 12, 18, 24, and 36 months after TBI. SETTING Patients with moderate to severe TBI discharged from 3 level-1 trauma(More)
OBJECTIVES The aim was to study changes over time for multiple outcomes based on the International Classification of Functioning, Disability, and Health in patients with aneurysmal subarachnoid hemorrhage and to compare long-term outcomes with norms. DESIGN A prospective cohort study with 4-yr follow-up was conducted. Main outcome measures were as(More)
