However, this approach did not appear to improve the possibility to identify cancer-susceptible subjects on the basis of the response to radiation exposure; the differences between cases and controls was not significantly increased in family positive and BRCA positive as compared with family negative and BRCA negative.
However, with increasingly severe environmental exposures, the difference between genotypes increases.
Moreover, a lowered odds ratio was found for infants in the second to fourth exposure category of prenatal di- ortho PCB exposure, although the difference between the highest exposure category and the reference category only showed borderline statistical significance (Table 5).
However, this was only a small part of the total exposure as the difference between PM2.5 exposure scenarios were about or less than 0.5 μgm-3 while the total exposure in the study area is about 10 μgm-3 [ 24].
For comparability, we calculated trimester results in Table 4 for an increment of exposure based on the IQR for gestational exposure, representing the difference between 75th and 25th percentiles.
In our study, where we calculated exposure risk, the difference between children who were asthmatic s and non-asthmatics showed no significant differences in exposure; however this is not to say the physiological effect of the same dose will not be different within the two groups.
Standard setters in the United States allow an institution to survey all the contracts it has with a trading partner and compute exposure as the difference between winning trades and losing ones.
Changes attributable to exposure are the difference between postexposure and preexposure for BAd, ET-1, and catecholamines.
For the first five exposures, the differences between the mean HC and C intake on day 1, 4 and 5 were statistically significant (T14s>3.36, Ps<0.005), but the differences on days 2 and 3 did not meet the adjusted alpha criterion (k = 10 comparisons, α' = 0.0051; Pd2 = 0.007, Pd3 = 0.009; Fig. 8).
On the other hand, residents of the high-exposure area may have been more vigilant in avoiding exposure, which would reduce the difference between the exposure areas.
