Related to false-negative rate: false negative error, True positive


Value, measure, or degree; a charge, payment, or price determined through the application of a mathematical formula or based upon a scale or standard.

For example, an interest rate is determined by the ratio between the principal and interest.

Rate is also used synonymously with tax.

demand equality in the false-positive and false-negative rates for each
In conclusion, the low correct interpretation rate and high false-negative rate for AIS reveals the difficulty in interpreting AIS on all types of cytology preparations and reflects room for improvement in the interpretation of AIS.
To sum up, the false-negative rate of the proposed measurement not only is low but also can be adjusted according to different requirements of the distance gap and false-negative rate.
We then describe the false-negative rate after sequentially including imputed and edited values.
Different lymphatic patterns may help to explain some important unresolved clinical problems, including different detection rates in different studies and high false-negative rates of about 10% in multicenter randomized controlled trials [7].
On the downside, the procedure is highly operator dependent, requires special training by a pathologist and is associated with an appreciable false-negative rate of 9.6%.
There is a high false-negative rate in this situation [22], This has been contradicted by a study performed in Cremona, Italy, where researchers were able to show that neoadjuvant chemotherapy does not alter the location of sentinel lymph nodes and they demonstrated a high pick-up rate before and after neoadjuvant chemotherapy [23], A meta-analysis in support of SLNB post neoadjuvant therapy on 1273 patients from 21 small studies showed an overall SLN detection rate of 90%, sensitivity 88%, specificity 100%, and false-negative rate of 12% [24], This compares very well with three meta-analyses of SLNB in patients who had not received neoadjuvant chemotherapy [25,26], with a highest detection rate of 96% and a false-negative rate of 7% in one of the studies [27].
Defining as in the text the false-negative rate to be the probability of failing to detect a true raised risk (i.e., 1--sensitivity), and the false-positive rate to be the probability of false detection of a background area as corresponding to a raised risk (i.e., 1--specificity), the three loss functions used are as follows:
Methadone had the highest sensitivity and specificity at 96% and 99%, with a false-negative rate of 3.9% and a false-positive rate of 1.2%.
The false-negative rate (HSIL misinterpreted as negative) was 0.9% (519 of 59 140) for PAP-PT, lower than that for PAP-Edu (1.0%; 266 of 28 000).
Therefore, small size and low number of tumours could potentially account for the high false-negative rate (38%) seen in this study when accessing NMP22's ability to detect early carcinogenesis or subclinical recurrences.
Troponin testing, for example, has proven valuable because its false-negative rate is low.
