As a result, there was low power to detect differences of the order of 10% (power < 50%) for all analyses, except the comparison of specificity between the age classes for the two serological tests.
The flows of people between the age classes determine the dynamic requirements for residential housing and commercial spaces in the community.
The clustering by age was statistically significant (P test in UniFrac: P = 0.007), although the clusters did not represent evolutionary divergence of bacteria between the age classes (Unifrac significance: P = 0.104).
The latter is defined between 0 and min{ α, η(1 − α)}, and regulates the degree of assortativity between the age classes [ 26], with ε → 0 indicating high assortativity and ε → min{ α, η(1 − α)} indicating low assortativity, as schematically shown in Figure 2. Table 1 reports the list of variables and parameters used to introduce the age classes.
A significant difference in abomasal parasite burden was seen between the age classes where greater burdens were associated with increasing age of hosts.
Comparison of the age classes between glioma patients and controls revealed significant differences in the seropositivity, which was higher in glioma patients, in all classes except the 21 30 years class which was higher in the control group (91.67%) than that of glioma patients (80%).
For cattle the geographical patterns of trade between counties were quite similar for different age classes of cattle, with by far the most trade in the age class below six months of age (detailed data not shown).
However, an exception to this is when there are two age classes of a given species between which there is no vertical overlap.
A logistic regression model fitted to the Brock test results as a function of the age class and duration factors indicated no significant differences in the sensitivity of the Brock Test between age classes (cub, yearling, adult) when adjusted for the 'duration categories' (P = 0.247).
