He thus minted improved sterling coins and fixed their value in relation to a gold standard.
A handheld computerized device based on urinary estrogen metabolites and LH has also been shown to be reliable in relation to biologic gold standards and to be effective in field studies [ 13, 16- 19].
This study deals with a diagnostic validation of the pre-treatment values of erythrocyte indices and serum ferritin (studied tests) in relation to the gold standard 'responsiveness to therapeutic test with oral iron' in women with low-risk singleton pregnancy.
Explicit targeting of a specific point along the chain of events leading to death is useful in terms of data collection and analysis and may allow more useful discussions of new methods in terms of adequacy for purpose rather than absolute validity in relation to dubious gold standards (40, 49).
In the light of our results, securin may prove to be a valuable prognostic factor for clinical pathology, although the present data do not yet allow for testing of the possible prognostic value of securin in relation to the gold standard of breast cancer prognostics, the Nottingham Prognostic Index (Elston and Ellis, 1991).
In light of these morphological and statistical findings, Cdc20 and securin seem to be potential prognosticators for clinical pathology, although the present data does not yet allow testing for their prognostic value in relation to the gold standard of breast cancer prognostication, the Nottingham Prognostic Index (Elston and Ellis, 1991).
Table 5 exhibits the sensitivity and specificity of MSP analysis in relation to the gold-standard cytological evaluation for tumor recurrence detection.
Chromagar KPC has sensitivity of 100%, specificity of 100%, PPV of 100%, NPV of 100% all in relation to PCR as gold standard.
In relation to the CPRD GOLD approximately 75% of the contributing practices in England (the CPRD currently only draws data from practices in England), or roughly 55% of all practices in the database are available for linkage.
The ability of CO to enhance the adsorption of OH on gold is discussed in relation to the surface structure of gold and changes in the work function as induced by the adsorption of CO.
