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.
The Bayley-III Cognitive and Language scales are good predictors of preschool mental test performance. [3] These scores are largely used for screening, helping to identify the need for further observation and intervention, as infants who score very low are at risk for future developmental problems. [3]
Gleason scores are often grouped together, based on similar behaviour: Grade 2-4 as well-differentiated, Grade 5-6 as intermediately-differentiated, Grade 7 as moderately to poorly differentiated (either 3+4=7, where the majority is pattern 3, or 4+3=7 in which pattern 4 dominates and indicates less differentiation., [6] and Grade 8-10 as "high ...
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 ...
A Perceptual Reasoning Index (PRI) can be derived from the raw scores on the Matrix Reasoning and Block Design subtests. A Full Scale IQ-2 (FSIQ-2) can be derived from the raw scores on the Matrix Reasoning and Vocabulary subtests, while a Full Scale IQ-4 (FSIQ-4) can be derived from the raw scores on all 4 subtests. WASI-II Subtests grouped by ...
Methods exist to derive a predicted mortality from this score, but these methods are not too well defined and rather imprecise. APACHE III is an updated version. SAPS II was designed to provide a predicted mortality, that does not reflect the expected mortality for a particular patient, but is good for benchmarking .
70-79 years old: +3 points; 80 years old or more: +4 points; Scores are summed to provide a total score to predict mortality. Currently 17 categories are considered in the popular Charlson/Deyo variant, [7] instead of 19 in the original score. [8] The weights were also adapted in 2003. [9]
The goal of a forecaster is to maximize the score and for the score to be as large as possible, and −0.22 is indeed larger than −1.6. If one treats the truth or falsity of the prediction as a variable x with value 1 or 0 respectively, and the expressed probability as p , then one can write the logarithmic scoring rule as x ln( p ) + (1 − ...
