The Simes 22 procedure to control for false-discovery rates was used to control for multiple comparisons across age categories within the analysis of invasive mechanical ventilation, charges and length of stay, yielding critical p values for significance of 0.028, 0.036 and 0.024, respectively.
A two-tailed Fisher's exact test comparing the frequency of multiple-virus infections between age categories gave a P value of 0.009, indicating that there were significantly more multiple infections in older animals.
Gene ontology analysis revealed cholesterol metabolism ontology terms as highly and specifically enriched among genes associated with multiple age-related disease categories by GWAS (cellular component terms in Fig. ).
Finally, while our approach involved a GWAS P-value cut-off in the initial stage of analysis, it may also be possible to examine all GWAS SNPs for association with multiple age-related disease categories and rank them by Fisher's combined probability test P-value.
This seems to be the result of older age categories having large multiples of men to women, but the women are beginning to outnumber the men in the 20s age group of the field.
The occurrence of single and multiple viral infections in pigs of different age categories was also investigated.
Unfortunately over-dispersion could not be evaluated because multiple records belonged to each dog, as the dogs moved through the age categories.
In particular, multiple comparisons of means (Tukey's test) give high statistical significance for the contrast between age categories 21 35 and >65 (p≦0.001), and between occupied and retired respondents (p≦0.05).
The pairwise multiple comparisons for age showed that there was no significant difference among the three younger age categories except between 5 14 and 15 24 years.
Interactions between acne and gender were tested under multiple logistic regression models using an added interaction term (acne × gender) and main covariates, age categories.
Table 3 displays the correlation between cesarean rates in singletons and multiples and the overall rate; we examined these associations in each of our gestational age categories.
