If people, pigs, and aquatic birds are the principal variables associated with interspecies transfer of influenza virus and the emergence of new human pandemic strains, influenza surveillance in these species is indicated.
Deliberation time, delay aversion (the difference in risk taking between ascending and descending conditions) and risk adjustment (the rate at which subjects vary risk taking in response to the ratio of red to blue boxes on each trial) are the principal variables of interest.
The P-value of the coefficient for the linear effect of peptone concentration was 0. 0081 and trace metals solution was less than 0.0001, suggesting that these were the principal variables with significant effect on the hyperthermophilic esterase production.
We therefore propose that primary productivity is the principal variable determining the disparate distributions observed.
The results of our case-control study demonstrate that the interaction between minimal distance to the nearest lake and wetland minimal distance to the nearest national highway, and the annual average precipitation are the principal environmental variables contributing to the spread of HPAI H5N1 virus in mainland China.
These slow variables are the principal and quadrature vibration amplitudes, precession rate and a phase angle.
The first aim was to identify the environmental variables that are the principal drivers of fruit transpiration in kiwifruit.
The item exhibiting the highest correlation with the ADLs was considered the principal variable, while the remainder was treated as modifying variables.
Measures of intermediate outcomes (A1C, BP, LDL levels) of diabetes care in patients of providers extracted from the electronic medical record were the principal dependent variables.
Logistic regression analysis, using the Akaike Information Criterion methodology, demonstrated that study drug and baseline APACHE II score were the principal independent variables determining this outcome, reflecting pharmacological and host factors, respectively.
As reflected in Table 2, given that physical health exhibits the highest correlation with ADLs, this variable was considered the principal variable in the logistic regression analysis, while mental health, age, sex, marital status, education and personal finances were treated as modifying variables.
