BACKGROUND Recent studies have shown an association of short-term exposure to fine particulate matter (PM) with transient increases in blood pressure (BP), but it is unclear whether long-term exposure has an effect on arterial BP and hypertension. OBJECTIVES We investigated the cross-sectional association of residential long-term PM exposure with arterial(More)
Appropriate data quality is a crucial issue in the use of electronically available health data. As source data verification (SDV) and feedback are two standard procedures for measuring and improving data quality it would be worthwhile to adapt these procedures to a current level of quality in order to reduce costs in data management. This project aims to(More)
BACKGROUND Studies investigating the link between long-term exposure to air pollution and incidence of diabetes are still scarce and results are inconsistent, possibly due to different compositions of the particle mixture. We investigate the long-term effect of traffic-specific and total particulate matter (PM) and road proximity on cumulative incidence of(More)
A literature review was done within a revision of a guideline concerned with data quality management in registries and cohort studies. The review focused on quality indicators, feedback, and source data verification. Thirty-nine relevant articles were selected in a stepwise selection process. The majority of the papers dealt with indicators. The papers(More)
Unfortunately, the original version of this article [1] contained an error. The paragraph of the results starting with " The relative risks… " contained errors in the reported effect estimates and confidence intervals. The paragraph read: The relative risks from the unadjusted crude model and for the main model are shown in Table 2. When expressing RRs per(More)
