Benchmark dose calculation from epidemiological dataE Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, Denmark
Biometrics 57:698-706. 2001..We therefore recommend that several sets of biologically relevant default settings be used to illustrate the effect on the benchmark results and to stimulate research that will guide an a priori choice of proper default settings...
Estimation of the benchmark dose by structural equation modelsEsben Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, Øster Farimagsgade 5, entrance B, PO Box 2099, DK 1014 Copenhagen K, Denmark
Biostatistics 8:675-88. 2007..This methodology is illustrated with the data on neurobehavioral effects in children prenatally exposed to methylmercury, where results based on standard regression models cause an underestimation of the true risk...
Confounder selection in environmental epidemiology: assessment of health effects of prenatal mercury exposureEsben Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, and Faroese Hospital System, Torshavn, Faroe Islands
Ann Epidemiol 17:27-35. 2007..Whereas standard analysis usually is conducted as if the confounders were known a priori, selection uncertainty also must be taken into account...
Effects of exposure imprecision on estimation of the benchmark doseEsben Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, Denmark
Risk Anal 24:1689-96. 2004..Methods that allow this adjustment are described and illustrated in data from an epidemiological study on the health effects of prenatal mercury exposure...
Consequences of exposure measurement error for confounder identification in environmental epidemiologyEsben Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, Blegdamsvej 3, DK 2200 Copenhagen N, Denmark
Stat Med 22:3089-100. 2003..These difficulties in statistical model development are illustrated by examples from a epidemiological study performed in the Faroe Islands to investigate the adverse health effects of prenatal mercury exposure...
Estimation of health effects of prenatal methylmercury exposure using structural equation modelsEsben Budtz-Jørgensen
Department of Biostatistics, University of Copenhagen, Blegdamsvej 3, DK 2200 Copenhagen, Denmark
Environ Health 1:2. 2002..This approach was used in a large epidemiological data set from a prospective study of developmental methyl-mercury toxicity...
Separation of risks and benefits of seafood intakeEsben Budtz Jørgensen
Department of Biostatistics, Institute of Public Health, University of Copenhagen, Copenhagen, Denmark
Environ Health Perspect 115:323-7. 2007..In resolving this conundrum, most epidemiologic studies provide little guidance because they address either nutrient benefits or mercury toxicity, not both...
The Precautionary Principle and statistical approaches to uncertaintyNiels Keiding
Department of Biostatistics, Institute of Public Health, University of Copenhagen, Copenhagen, Denmark
Int J Occup Med Environ Health 17:147-51. 2004..The recent methodology of the Bayesian model averaging might be a systematic version of this, but is this an arena for the Precautionary Principle to come into play?..
Heritability of Tpeak-Tend interval and T-wave amplitude: a twin studyChristian Haarmark
Laboratory of Experimental Cardiology, University of Copenhagen, Copenhagen, Denmark
Circ Cardiovasc Genet 4:516-22. 2011..Heart rate and QT interval are known to be heritable traits. The heritability of T-wave morphology parameters such as TpTe and Tamp is unknown. TpTe and Tamp were evaluated in a large sample of twins...
Group cohesion and social support in exercise classes: results from a danish intervention studyUlla Christensen
Department of Social Medicine, Institute of Public Health, University of Copenhagen, Blegdamsvej 3, DK 2200 Copenhagen N, Denmark
Health Educ Behav 33:677-89. 2006..Manipulating group dynamics may be a promising intervention tool in the promotion of leisure-time physical activity...

Institute of Preventive Medicine, Copenhagen University Hospital and Center for Health and Society, University of Copenhagen, Copenhagen K, Denmark
Am J Epidemiol 169:1167-78. 2009..These results suggest that increases in body size prior to age 11 years are less harmful to adult blood pressure than increases occurring after this age...
Exhaled nitric oxide measure using multiple flows in clinically relevant subgroups of COPDNassim Bazeghi
Department of Cardiology and Respiratory Medicine, Hvidovre Hospital and Faculty of Health Sciences, University of Copenhagen, Copenhagen, Denmark
Respir Med 105:1338-44. 2011..This study questions the relevance of using FeNO as a biomarker to evaluate local inflammation in COPD and points to a need for developing novel non-invasive biomarkers for research laboratory work and daily clinical practice...
