What does specificity mean, and what does high specificity mean

A clear distinction between a standard and a comparator. (e.g., there is specificity for each individual).

In general, it is a numeric value that represents the size of the difference.

Specificity refers to the purpose of scientific anti-cancer by cultivating the patient's own anti-cancer cells in vitro and then infusing them back into the patient's body. Specific and unique ** mode, what cells are missing in the patient's body, what cells are cultured, more targeted.

With the help of biological agents, it is cultivated and injected into the human body, and the most efficient specific immune cells DC, CIK, T and NK cells in the human body work together to mobilize the defense mechanism of the patient's body, so as to regulate the biological response of the patient's body, kill cancer cells, activate immune cells, and kill the remaining tiny cancer cells in the body, so as to achieve the purpose of starting the tumor from the root.

High specificity means that the opposite sex is a relatively large time, looking for some of his friends of the opposite sex, fate is still better.

The specificity of an antibody refers to the substance that recognizes a similar antigen or a specific antigen. The higher the specificity of the antibody, the stronger its antibody recognition ability, that is, the greater the role it will play.

Sensitivity is the chance of not being misdiagnosed (false negative) in the case of a confirmed disease, and specificity is the probability of a good diagnosis (positive) when a certain disease is diagnosed. If the sensitivity of the diagnosis is increased, the specificity of the diagnosis will be reduced, that is, the reduction of misdiagnosis will inevitably increase the misdiagnosis, and vice versa.

The sensitivity and specificity of a certain index is the probability that a person who is originally sick can be identified by this finger mark and also diagnosed as a sick person. Specificity is the probability that a person who is not sick is identified by this indicator, and it is also diagnosed as a person who is not sick.

Medical statistics is a discipline that uses the principles and methods of probability theory and mathematical statistics, combined with medical practice, to study the collection, collation, analysis and inference of numerical data. The object of medical research is mainly the human body and various factors related to human health.

Peculiarities of medical statistics.

The same is true for the statistical analysis of medical data, if a certain index is missing, the missing data is filled in by the corresponding method, the difference between the statistical results before and after the filling is compared, and the change of the widening and defeat analysis is discussed, which can be called sensitivity analysis.

For example, in clinical trials, multiple statistical analysis datasets (such as PPS, FAS, and SS) are often defined and formed, and each dataset has specific functions and application rules, but the comparison of the results of multiple datasets can also be called sensitivity analysis to a certain extent. Similarly, whether it is necessary to include a central effect term in the statistical analysis of multicenter clinical studies is also the scope of sensitivity analysis.
