The sensitivity analysis revealed that number of infected, but undetected domestic herds and the multiplicative between-survey-spread factor were most correlated with the pre-survey probability of freedom from infection and the resulting sample size, respectively.
Interactions for a multiplicative effect between genes or between environmental factors and genetic polymorphisms were tested with a case-only approach.
Added research on the potential for additive or multiplicative interactions between exposures to multiple environmental agents on male reproduction is also needed.
Among the employment status groups, we found significant multiplicative interactions between unemployed individuals and gender as well as between retired individuals and gender.
When testing the multiplicative interaction between DM II and smoking, we observed a significant interaction between DM II and smoking (P for interaction=0.03).
A test for multiplicative interaction between leptin and CRP was performed based on the suggested correlation between the two variables 21.
We found an expected multiplicative interaction between parameters.
We noted a multiplicative interaction between ever having smoked regularly and GSTO1 (ORinteraction = 0.55, 95% CI: 0.33 0.92) and GSTO2 (ORinteraction = 0.54, 95% CI: 0.32 0.90).
In the closed-loop approach, the models are identified so that the multiplicative error between real and nominal closed-loop sensitivity functions is minimized.
