| breath analysis test | A test of hepatic and intestinal absorptive function; aminopyrine labelled with radioactive carbon is administered orally; expired 14CO2 is a measure of aminopyrine absorption and its metabolism in the liver; a measurement of the amount of 14CO2 exhaled after an oral dose of 14C-O-xylose; a measurement of exhaled hydrogen gas following an oral dose of lactose as a test of lactose deficiency.

| gastric analysis | Measurement of pH and acid output of stomach contents; basal acid output can be determined by collecting the overnight gastric secretion or by a 1-hr collection; maximal acid output is determined following injection of histamine; output is measured by titration with a strong base.

| matched-pair analysis | A type of analysis in which subjects in a study group and a comparison group are made comparable with respect to extraneous factors by individually pairing study subjects with the comparison group subjects (e.g., age-matched controls). (12 Dec 1998) |
| regression analysis | Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see linear models) the relationship is constrained to be a straight line and least-squares analysis is used to determine the best fit. In logistic regression (see logistic models) the dependent variable is qualitative rather than continuously variable and likelihood functions are used to find the best relationship. In multiple regression the dependent variable is considered to depend on more than a single independent variable. (12 Dec 1998) |
| path analysis | A mode of analysis involving assumptions about the direction of causal relationships among linked sequences and configurations of variables. (05 Mar 2000) |
| pedigree analysis | The formal study of the pattern of a trait in a pedigree to determine such properties as its mode of inheritance, age of onset, and variability in phenotype. (05 Mar 2000) |
| volumetric analysis | Quantitative analysis by the addition of graduated amounts of a standard test solution to a solution of a known amount of the substance analyzed, until the reaction is just at an end; depends upon the stoichiometric nature of the reaction between the test solution and the unknown. (05 Mar 2000) |
| cephalometric analysis | A study of the skeletal and dental relationships used in orthodontic case analysis. (05 Mar 2000) |
| percept analysis | Psychologic survey of an individual's personality using Rorschach's series of inkblots. (05 Mar 2000) |
| character analysis | Analysis of the defenses and personality traits that characterise an individual. (05 Mar 2000) |
| meta-analysis | <statistics> A quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness or to plan new studies. With application chiefly in the areas of research and medicine. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of the literature. (27 Jun 1999) |
| cluster analysis | A set of statistical methods used to group variables or observations into strongly inter-related subgroups. In epidemiology, it may be used to analyze a closely grouped series of events or cases of disease or other health-related phenomenon with well-defined distribution patterns in relation to time or place or both. (12 Dec 1998) |
| Western blot analysis | A procedure in which proteins separated by electrophoresis in polyacrylamide gels are transferred (blotted) onto nitrocellulose or nylon membranes and identified by specific complexing with antibodies that are either pre-or post-tagged with a labelled secondary protein. See: immunoblot. Synonym: Western blot, Western blotting. Origin: coined to distinguish it from eponymic Southern blot a. (05 Mar 2000) |
| combustion analysis | <technique> A method for determining the chemical composition of a compound by burning the compound under controlled conditions. Often used to determine the relative amounts of carbon and hydrogen in a compound. (09 Oct 1997) |
| multivariate analysis | A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables. (12 Dec 1998) |
