盛行率(prevalence)與發生率(incidence) 流行病學中描述疾病在人口中蔓延情形, 通常藉由疾病盛行率以及疾病發生 率(Incidence rate)描述, 其中疾病盛行率為單一時點或一段期間內罹患疾病人數佔總人口數的比例; 盛行率(epidemiology): the ratio (for a given time period) of the ...
Although cancer incidence in this region is lower than the USA or Europe, the death rate from cancer is almost twice as high as the USA.doi:10.1038/nrclinonc.2013.77NoneNature Reviews Clinical OncologyEpidemiology: epidemic rates of cancer incidence in Latin America," Nature Reviews Clinical ...
Incidence Rate in Market Research Apart from the epidemiology definition, incidence rate measures the occurrence or percentage of individuals who are eligible to participate in a study. For example, in a study of Canadians, if the eligibility of research is defined as people who ownAppleproducts, ...

Both incidence and prevalence were higher in women than men. The incidence of any-OA decreased gradually in the past 20 years at an annual rate of −1.6% (95%CI -2.0 to −1.1%), and the reduction speeded up for people born after 1960. The prevalence of any-OA increased gradually ...
When the traditional assumption that the incidence rate is proportional to the product of the numbers of infectives and susceptibles is dropped, the SIRS model can exhibit qualitatively different dynamical behaviors, including Hopf bifurcations, saddle-node bifurcations, and homoclinic loop bifurcations. ...
the importance of knowledge about incidence and mortality of oral cavity and lip cancer in health planning, this study was performed with the aim of investigating the incidence and mortality rate of oral cavity and lip cancer and its relation with the Human Development Index in the world in ...
This study presents the methods used and the incidence rates found for severe injury (causing hospitalisation or death) in a population of 89 000 children under age 17 years in northern Manhattan, a largely poor area of New York City. The average annual incidence rate (measured from 1983 to ...
The term incidence rate refers to the rate at which a new event occurs over a specified period of time. Put simply, it describes the frequency at which new incidents occur. This measure is commonly used in epidemiology as a way to denote the occurrence of disease, illness, or accident. Th...
Fibrosis progression proportion, and mean annual rate of progression in NASH were 40.76% (95% CI: 34.69-47.13) and 0.09 (95% CI: 0.06-0.12). HCC incidence among NAFLD patients was 0.44 per 1,000 person-years (range, 0.29-0.66). Liver-specific mortality and overall mortality among NAFLD ...
