The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]
The International Prognostic Index (IPI) is a clinical tool developed by oncologists to aid in predicting the prognosis of patients with aggressive non-Hodgkin's lymphoma. Previous to IPI's development, the primary consideration in assessing prognosis was the Ann Arbor stage alone, but this was increasingly found to be an inadequate means of ...
SOFA was designed to provide a simple daily score, that indicates how the status of the patient evolves over time. Glasgow Coma Scale (also named GCS) is designed to provide the status for the central nervous system. It is often used as part of other scoring systems. FOUR score - 17-point scale for the assessment of level of consciousness. Aims ...
Gleason score 3+4=7 (prognostic grade group II) indicating the majority is pattern 3; Gleason score 4+3=7 (prognostic grade group III) where pattern 4 is dominant; [6] Gleason score 4+4=8 (prognostic grade group IV); Gleason scores 9-10 (prognostic grade group V). [7] Prostate cancers with a Gleason score ≤ 6 usually have rather good prognoses.
The Framingham Risk Score is a sex-specific algorithm used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score was first developed based on data obtained from the Framingham Heart Study , to estimate the 10-year risk of developing coronary heart disease. [ 1 ]
