Embodiment Construction

[0020] When the importance of sensitivity and specificity is different (this is a very real problem in the evaluation of diagnostic tests), the existing evaluation methods of diagnostic tests cannot meet the actual needs of diagnostic method evaluation in clinical medicine, and there are methodological limitations. Major flaw. The weighting method established by the present invention starts from practical application and has strong practicability. The product index is weighted, which is a pioneering research. The specific steps of the present invention will be described below.

[0021] Such as figure 1 As shown, two diagnostic tests that are independent of each other and one with higher sensitivity than the second but lower specificity than the second are firstly selected: A diagnostic test and B diagnostic test.

[0022] The results of the diagnostic tests are shown in Table 1. The vertical axis refers to whether the individual tested by the "gold standard" or reference stan...

Abstract

The invention discloses a diagnosis testing evaluation method based on the weighted product index model. The diagnosis testing evaluation method comprises the steps that a weighted product index model of arbitrary weights based on sensitivities and specificities is built, when the significances of the sensitivities and the specificities are different, the true values of the diagnoses can be reflected, the practicality is good, the programmed model procedures are simple, which is convenient for a clinical doctor to use, and the set up of the model will provide a new and more powerful statistical analysis tool for diagnosis testing evaluations.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a diagnostic test evaluation method based on a weighted product index model with arbitrarily assignable sensitivity and specificity. Background technique [0002] Diagnostic testing is of great importance to healthcare, as is its impact on healthcare costs. An important problem that needs to be solved in the clinical diagnosis and treatment of patients is whether the patient is sick and what kind of disease he is suffering from. In confirming and excluding the diagnosis, it is necessary to choose a reasonable diagnostic test; in addition, in screening asymptomatic patients, follow-up , judging disease severity, estimating prognosis, and response to treatment all require selection of diagnostic tests based on their precision, accuracy, patient acceptability, safety, and cost. These are the most frequently encountered problems in clinical practice [0003] Since Yerushalmy prop...
