It gave an overall ERR for lung cancer of 0.21 %/WLM, which was modified by time since exposure, attained age, and exposure rate.
We based the analyses on a detailed summary table of the number of deaths and person years stratified by dose, city, sex, and five year intervals of age at exposure, attained age, and follow-up period.
The modifying effects of characteristics at exposure, attained age, and time since examination on the estimates of ERR (for the primary end points) are presented in Supplementary Table 6.
Despite the increase in aprepitant plasma concentrations in patients receiving 375 mg dose relative to exposure attained during our previous study at lower doses, we think this dose is still too low to observe an antiviral effect based on the target concentrations required to elicit an antiviral effect from in-vitro and preclinical experiments [ 49].
The effects of occupational exposure to diesel and gasoline emissions were modeled using 5 exposure metrics: ever exposure, highest attained exposure concentration, duration of exposure, frequency of exposure, and cumulative exposure.
Here, transformation results in concurrent bioactivity removal, and there is a clear degree of reaction progress where the risks associated with contaminant exposure attain acceptable levels.
Focusing on mitochondrial complex (MC) I, II, III, IV, and V composition genes, some of MC I and II genes were slightly down-regulated; however, all MC I and II coding genes were up-regulated from 24 h after algicide exposure, attaining >2-fold changes at 48 h.
The aim of the present analysis was to evaluate the lung cancer risk associated with radon and its progeny due to cumulative radon exposure, exposure rate, duration of exposure, time since exposure, and attained age.
Previous analyses on the relationship between lung cancer and cumulative radon exposure in the Wismut cohort provided evidence for a model that is linear in radon exposure with the exponential effect modifiers age at median exposure (or attained age), time since median exposure and radon exposure rate (Walsh et al, 2010a, 2010b).
Age at exposure, time since exposure, and attained age are collinear variables, and their combined effect differs from the individual effects of each factor.
In a review of estimated exposure doses to the brain in eight cohort studies no effect modification on the risk by sex, age at exposure, time since exposure or attained age was observed [ 5].
