These parameters and their uncertainties were derived from a reference population.
This study aims to establish joint fluid reference levels for Chromium (Cr) and Cobalt (Co) in a reference population of available fluid types.
There is a lack of appropriate questionnaires collecting indicators of health status and health care, which enable a meaningful comparison with a reference population.
The Collaborative Cross (CC) is a revolutionary genetic resource comprised of a reference population of hundreds of mouse lines descended from eight genetically and phenotypically diverse founder strains.
Indicators of riparian ecosystem condition for headwater coastal plain streams were identified from data obtained from a reference population of reaches ranging widely in ecological condition.
Software then compares this data to data from a reference population -- people of similar weight, age and height -- stored in the processing unit's memory and calculates body composition (usually displayed as the percentage of tissue that is fat).
Compared with a reference population of patients with ET, survival was progressively shortened depending on fibrosis grade, with hazard ratio (HR) of 1.8, 2.8, 5.3, and 6.2 for fibrosis grade 0, 1, 2, and 3, respectively.
A reference population from Denmark is available [19].
Population completeness evaluates missing values with respect to a reference population.
Child stunting is measured by comparing child length for age with a reference population, where a child whose length for age is less than minus two standard deviation of a reference population is considered stunted.
In particular, it is often not possible to extrapolate the results to a reference population, thus greatly restricting their relevance.
