Finally, our data leads to the hypothesis that RSV and HMPV not only induce antidromic immune reactions in the individual age groups but that these effects invert in the aged animals, thus being double-antidromic with respect to age and virus specific immune response.
Smoking rates fell for each of the individual age groups surveyed, most notably among eighth graders - from 6.1percentt in 2011 to 4.9percentt in 2012, the survey found.
While they cannot derive the average cost by individual age groups, they can still calculate the total average prescribing cost (total pharmaceutical expenditure divided by total assisted population).
By individual age groups and sex, females who did not test had higher mortality than those who tested, with the difference in the age group 45 49 being statistically significant (Figure 2).
Here again and also at the two studied CpG sites (in the F8 locus), we could clearly see significant differences in all age groups combined as well as in the individual age groups (apart from a border line significance at CpG7 for age group 51 64 (p = 0.053).
The chi-square test (not shown) for the differences in mortality rates between tested and untested in Table 2, does not attain significance in individual age groups (because of relatively small numbers), however, for both sexes combined, and for males and females of all ages (except for males aged 35 44) the mortality rates in the untested group are higher than in the tested group.

However, the relatively small sample size of individual age group in our survey, especially among those aged 11 years, may introduce potential bias.
Sepsis and vancomycin use were found to be highly associated with AKI in the overall cohort as well as for each individual age group.
The individual age group differences do not reach statistical significance, but overall mortality is significantly higher in the untested group than in the tested, due not only to differences in the age and sex composition of the tested and untested groups, as can be shown by direct standardisation.
There is no theoretically best practice with regard to the number of age groups, their width and the boundaries of the individual age group classifications.
The division into age groups does, of course, reduce the numbers and therefore the statistical power in each individual age group.
