- 22 July 2010
The quality assessment of non-randomized studies is an important component of a thorough meta-analysis of nonrandomized studies. Low quality studies can lead to a distortion of the summary effect… Expand
Residential exposure to traffic is associated with coronary atherosclerosis.
BACKGROUND Long-term exposure to fine-particulate-matter (PM2.5) air pollution may accelerate the development and progression of atherosclerosis. We investigated the associations of long-term… Expand
Assessment of clinically silent atherosclerotic disease and established and novel risk factors for predicting myocardial infarction and cardiac death in healthy middle-aged subjects: rationale and…
BACKGROUND In view of consistently high cardiovascular morbidity and mortality rates, international efforts are aimed at developing tools for more precise risk prediction to allow preventive… Expand
