Previous studies have suggested an association between exposure to 50-60 Hz magnetic fields (EMF) and childhood leukaemia. We conducted a pooled analysis based on individual records from nine studies, including the most recent ones. Studies with 24/48-hour magnetic field measurements or calculated magnetic fields were included. We specified which data(More)
CONTEXT Previous reviews of associations of apolipoprotein E (apoE) genotype and coronary disease have been dominated by smaller studies that are liable to biases. OBJECTIVE To reassess associations of apoE genotypes with circulating lipid levels and with coronary risk. DATA SOURCES We conducted an updated meta-analysis including both published and(More)
To identify risk variants for glioma, we conducted a meta-analysis of two genome-wide association studies by genotyping 550K tagging SNPs in a total of 1,878 cases and 3,670 controls, with validation in three additional independent series totaling 2,545 cases and 2,953 controls. We identified five risk loci for glioma at 5p15.33 (rs2736100, TERT; P = 1.50 x(More)
BACKGROUND Radiofrequency exposure from mobile phones is concentrated to the tissue closest to the handset, which includes the auditory nerve. If this type of exposure increases tumor risk, acoustic neuroma would be a potential concern. METHODS In this population-based case-control study we identified all cases age 20 to 69 years diagnosed with acoustic(More)
A case-control study was conducted to test the hypothesis that exposure to magnetic fields of the type generated by high-voltage power lines increases cancer incidence in children. The study base consisted of everyone under age 16 years who had lived on a property located within 300 meters of any of the 220 and 400 kV power lines in Sweden during the period(More)
An editorial in this issue explains that the degree of biological interaction between risk factors is measured as the deviation from additivity by the corresponding disease rates and not for example as deviation from multiplicativity. It is the purpose of this article to describe how a logistic regression model, or a Cox regression model, can be defined in(More)
Although it is known that overall mortality is increased after hip fracture, the influence of hip fracture risk factors on the subsequent mortality and cause of death has not been well studied. The objective of this study was to establish the survival after hip fracture in women and to assess the impact of comorbidity on mortality. We identified a complete(More)
CONTEXT Recent studies indicate common etiologies for cardiovascular disease (CVD) and osteoporotic fractures. OBJECTIVES To examine the relation between CVD and risk of hip fracture in twins and evaluate the relative importance of genetics and lifestyle factors in this association. DESIGN, SETTING, AND PARTICIPANTS A cohort of all 31,936 Swedish twins(More)
Handheld mobile phones were introduced in Sweden during the late 1980s. The purpose of this population-based, case-control study was to test the hypothesis that long-term mobile phone use increases the risk of brain tumors. The authors identified all cases aged 20-69 years who were diagnosed with glioma or meningioma during 2000-2002 in certain parts of(More)
OBJECTIVES Consolidation of epidemiological data on pancreatic cancer and worksite exposures. METHODS Publications during 1969-98 were surveyed. Studies without verified exposures were excluded. Meta-analyses were conducted on data from 92 studies covering 161 populations, with results for 23 agents or groups of agents. With a standard format, five(More)
