Confounding by indication is a term used when a variable is a risk factor for a disease among nonexposed persons and is associated with the exposure of interest in the population from which the cases derive, without being an intermediate step in the causal pathway between the exposure and the...
Later on, the researcher found out some parts of the puzzle were complicated to see for some of the older participants, making age a confounding factor because it impacted study results. What is an example of an extraneous variable? A researcher designs an empathy study to test how career ...
In a two-factor ANOVA test, if one variable has 10 levels and the other has 9 levels, how many degrees of freedom are there for the interaction? In a two-factor ANOVA test, if one variable has 5 levels and the other has 4 levels, how many degrees of ...
A strong correlation does not mean a cause-and-effect relationship. Causation is only one explanation of an observed association. What else could produce a strong correlation? a) Confounding factor b) Coincidence c) Common cause d) All of the above ...
The first demonstrates that there is a clear subjective feature bias that depends on the types of terrain being evaluated: Our participants found certain natural terrains to be more believable than others. This confounding factor means that any comparison experiment must not ask participants to ...
Thus, non-randomized comparative designs expose to unequal distributions of covariates that impact both the outcome and the decision to treat, so-called ”confounding by indication” [23]. Adjusted techniques of treatment estimation through the use of multivariate regression models have been widely ...
Another confounding factor is that non-hematopoietic cells and tumor cells may not have the same signaling networks found in erythroid-progenitor cells or may have constitutive activation of pathways. Either can render the cells nonresponsive to growth factor challenge. Thus, cells may not respond ...
Also, there are information that some infections can serve as a promoting factor, by ensuring conditions for the immune reaction on a drug to start, which otherwise could not be the case [5]. In addition to these explanations, the second result might also implicate the increased risk for ...
