Gold standard clinical variable

In the past complementary therapies have been called alternative or fringe medicine but the position of conflict between complementary and conventional therapies is outdated. The term allopathic is used for the conventional, orthodox mainstream medicine and relies on gathering evidence through scientific research methodology. It examines outcomes, i.e. the results or consequences that follow from the action or intervention that we call the treatment. There is a clinical criterion called the gold standard clinical variable, which is often viewed as the measure of clinical improvement in a condition. This can be a simple quantitative measure for some conditions, e.g. blood sugar level for diabetes, peak air flow for asthmatics. Often there are multiple variables and simple quantitative criteria are inapplicable. 

TBW derived from Watson (1980) anthropometries formula with TBW from the gold standard, deuterium oxide dilution method in healthy Colomhian young females. The purpose was to determine whether either or both of these clinic based measurement methods would allow for the accurate assessment of body composition. Subjects underwent multifrequency BIA measurements, on the dominant side of the body, using an 800-pA and 50-kHz alternating current with a standardized tetrapolar technique. The BIA variables measured were R50 and XC50. The results show that TBW by anthropometry had a moderate coefficient of determination (r ) and was not statistically different from TBW by D20, however, the Cl were wider than 2 standard deviations (SD).
