Interactions between COPD-status and age at inclusion, year of birth, sex, SES, immigration status, the level of diagnosis and prior hospitalization on outcome were tested by entering interaction terms to the fully adjusted COX model.
Interactions between COPD status and age at inclusion, gender, and prior hospitalization on outcome were tested by entering interaction terms in the fully adjusted Cox models.
We also tested the interaction of aortic and coronary sum scores with section thickness (continuous) and the use of contrast agent (yes/no) by entering interaction terms into the model.
Tests for a statistical interaction between the parental bonding style and sex of the participants were conducted by entering interaction terms for the quadrants of parental bonding and the sex of the participants in multivariate model.
We examined associations between maternal PBDEs and neurobehavioral outcomes at different ages by entering interaction terms between PBDEs (continuous variable) and child age (categorical variable) in the mixed models.
Effect modification was assessed by entering interactions between drinking variables and occupation type in the fully adjusted logistic regression models.
While entering interactions in the online Curation Tool, biocurators also designate the source of the interaction as either being derived from the 'abstract' or the 'full text' (5).
The energy spread in the electron beam is due to interaction in the wiggler region, as electrons enter the interaction region at different phases relative to the EM wave.
Together these data suggest that there is an alternate restriction to replication, here called Lv3, that is encountered by viruses that enter via interaction with CD4 and an endogenous rhesus coreceptor.
Moreover, the dispersed phase and fluid particle velocity correlation, that enter the interaction terms describing the exchange of fluctuating energy between the phases, are compared with the result of Reeks' and Zaichik's theoretical expressions in the case of simple shear flow.
