Molecular epidemiology defined the extent of this large, cross-jurisdictional outbreak.
In conclusion, this study provides information on the epidemiology and the extent of rotavirus infections in Burkina Faso.
4 Although inapparent dengue has been reported in many countries, 5– 7 there is little data on its epidemiology or the extent of its severity.
Few large studies have been conducted to identify risk factors for CDI in the community-setting, and investigators have not determined if or to what extent the epidemiology of CA-CDI differs from that of HA-CDI.
The age of scoliosis onset in large extent determines its epidemiology, natural course and response to the treatment [ 19, 21- 23].
The CCR collected Surveillance Epidemiology and End Results (SEER) Extent of Disease (EOD) for breast cancer cases diagnosed from 1988 through December 2003 [ 11], and in 2004, began collecting Collaborative Staging data items [ 12].
Friis et al. [ 24] and Merrill et al. [ 18] explicitly state that an objective of epidemiology is to determine the extent of disease found in a community and to "identify where the public health problem is greatest" p5 [ 18].
IVF treatment efficacy was defined as DR per egg retrieval cycle since in general epidemiology efficacy refers to the extent to which a specific intervention, procedure, regimen or service produces a desired result.
In conclusion, cancer epidemiology is, to a large extent, the determination of small effects and weak associations, and poses major challenges that are easier to overcome in certain areas (e.g., genetic epidemiology) than in others (e.g., environmental or nutritional epidemiology).
Instead, environmental epidemiology is relying to an increasing extent on measurements of contaminant concentrations in human tissue samples (Grandjean 1995).
