The rate will be expressed as incidence density, calculated with the total number of incident STIs and total observation time.
It fell among 20- to 29-year-olds in England after the introduction of screening in 1988 before rising again as incidence in other age groups fell.
These can be expressed as incidence and/or prevalence.
Pancreatic cancer is one of the most lethal cancers as incidence approximates mortality [1].
When exponentiated, the β's can be interpreted as incidence rate ratios.
The inclusion of the population offset allows the exponentiated coefficients to be interpreted as incidence rate ratios.
Wider sociological aspects, such as incidence of domestic violence and mental health problems over time, would also be of interest.
This section analyzes the model econometrically, starting with the disease contraction probability q in equation (1), expressed as incidence.
Longer follow-up is necessary to determine long-term graft function as well as incidence of degenerative joint disease.
The exponential of this coefficient is defined as Incidence Rate Ratio, (operatorname{IRR}_{beta}(t) = e^{beta(t)}).
Additionally HOE do have the advantage of adding freedom to the optical design process, as incidence and exit angle can be chosen independently.
