Please enter your name. This assumption, though supported by extensive data from psychophysical and medical studies 9may not be true in general. In some cases, Se is more important than Sp, for example when a disease is highly infectious or associated with serious complications.
Diagnostic accuracy of calculated serum osmolarity to predict dehydration in older people: The general structure of a ROC curve. WorldCat is the world’s largest library catalog, helping you find library materials online. The views expressed are the sole responsibility of the authors.
The prevalence of dehydration among the studied population was considered 0. Employing a Bayesian approach, the post-test posterior probability of a disease depends on the pre-test probability of the disease and the test result.
However, in real world, a ROC curve is constructed based biocyemia a few discrete points. Hydration in the older hospital patient — is it a problem? Please select Ok if you would like to proceed with this request anyway. Index for rating diagnostic tests. Herein, we show that a proposed method that maximizes the weighted number needed to misdiagnose, an index of diagnostic test effectiveness we previously proposed, is the most appropriate technique compared to the aforementioned ones.

On determining the most appropriate test cut-off value: The higher the NNM of a test, the closer is the test to the gold-standard, hence, a better test. Clin J Oncol Nurs. The curve is confined in a unit square Figure 1.
It would therefore be feasible if we can figure out the coordination instead of the slope of the point on a ROC curve corresponding to the most appropriate cut-off value through an analytical method.
On determining the most appropriate test cut-off value: the case of tests with continuous results
Several criteria, mostly based on ROC analysis, have so far been proposed for choosing the most appropriate cut-off value 2511 – Search WorldCat Find items in libraries near you.
Besides the specimen to be analyzed, future autoanalyzers need to be fed with an estimate of pre-test probability based on the previous test resultsthe disease of interest, and the associated cost of misdiagnosis.

Several years later, the method was found useful in many other scientific disciplines including diagnostic medicine where a physician should discriminate a TP from a FP test result. Montgomery Perioperative medicine However, because of the discrete non-differentiable data set, we could not find the corresponding point solely based on knowing its slope without curve fitting.
