Also, it should be considered that prevalence data are difficult to combine since in endemic regions polyparasitism is common [ 1]; indeed, in these regions subjects infected with multiple helminths tend to harbor the most intense infections, possibly due to an additive and/or multiplicative impact on nutrition and organ pathology (reviewed in [ 7]).
The per-exposure cofactor provides the multiplicative impact of a given risk on HIV transmission probability per coital act.
The concerted presence of such biases may have a multiplicative, detrimental impact on the scientific literature.
Pattern A: multiplicative noise.
Finally, because of the multiplicative impact of selection over the life cycle, it is crucial to consider the entire life cycle for species whose viability is at stake.
For the respective Poisson model, the multiplicative impact factor is 1.0464 which means that for each increase of the minimum daily atmospheric pressure by 1 unit the probability of the day being a GDV day gets multiplied by the factor 1.0464.
In a combination of these two trends, acute and chronic diseases are leading to the emergence of global syndemics, wherein the interaction between two or more health conditions such as among diabetes, cardiopulmonary disease, and severe acute respiratory syndrome (SARS)—has a multiplicative rather than additive impact on human well-being (56).
IPAT, as a multiplicative identity, simply states that the impact any particular society will have on its environment is due equal parts to population size and distribution (P), level of affluence (A), and state of technological development (T) [24].

All rate data, except at 45 °C and 5% oxygen, fit well (r2=0.75) to a multiplicative Monod equation with terms describing the impact of oxygen, pH, temperature and ammonia concentration.
