Empirical research articles are a great resource of very specific statistical information and can lead to access of data in the results of the study. PubMed and CINAHL Plus, among others have statistical information indexed and with use of Medical Subject Headings and Sub-headings allows a searcher to focus a search containing this type of information.
PubMed is the premier database for bio-medical literature. Want to learn PubMed? With the use of Medical Subject Headings (MeSH) and sub-headings a query can be formulated. For example, to search for the survival rate for squamous cell carcinoma among African Americans a search can be built using the following steps.
The following video tutorial is a good source to help you understand and use PubMed effectively.
CINAHL stands for the Cumulative Index to Nursing and Allied Health Literature. Using CINAHL Headings can help you find more relevant and a greater number of results.
Economics - The science of utilization, distribution, and consumption of services and materials.
Epidemiology - Field of medicine concerned with the determination of causes, incidence, and characteristic behavior of disease outbreaks affecting human populations.
Incidence - The number of new cases of a given disease during a given period in a specified population.
Life Expectancy - Based on known statistical data, the number of years which any person of a given age may reasonably be expected to live.
Logistic Models - Statistical models which describe the relationship between a qualitative dependent variable (e.g. presence or absence of disease) and an independent variable.
Morbidity - The proportion of patients with a particular disease during a given year per given unit of population.
Mortality - All deaths reported in a given population.
Statistics and numerical data (sub-heading) - Used with non-disease headings for the expression of numerical values which describe particular sets of groups of data.
Survival Rate - The proportion of survivors in a group, e.g., of patients, studied and followed over a period, or the proportion of persons in a specified group alive at the beginning of a time interval who survive to the end of the interval.
Utilization (Sub-heading) - Used with equipment, facilities, programs, services, and health personnel for discussions, usually with data, of how much they are used.
