43 results about "Odds ratio" patented technology

An odds ratio (OR) is a statistic that quantifies the strength of the association between two events, A and B. The odds ratio is defined as the ratio of the odds of A in the presence of B and the odds of A in the absence of B, or equivalently (due to symmetry), the ratio of the odds of B in the presence of A and the odds of B in the absence of A. Two events are independent if and only if the OR equals 1: the odds of one event are the same in either the presence or absence of the other event. If the OR is greater than 1, then A and B are associated (correlated) in the sense that, compared to the absence of B, the presence of B raises the odds of A, and symmetrically the presence of A raises the odds of B. Conversely, if the OR is less than 1, then A and B are negatively correlated, and the presence of one event reduces the odds of the other event.

Methods of determining acute myeloid leukemia response to treatment with farnesyltransferase

We analyzed bone marrow from 67 patients from a phase 2 study of farnesyltransferase inhibition with tipifarnib (R115777, ZARNESTRA®), in older adults with previously untreated, poor-risk acute myeloid leukemia (AML) for N-Ras mutations, global gene expression, and / or quantitative PCR (qPCR) of specific genes. Microarray profiling identified a two-gene expression ratio (RASGRP1:APTX) which provided the greatest accuracy for predicting response to tipifarnib. We demonstrated that this classifier could predict response to tipifarnib in an independent set of 54 samples from relapsed or refractory AML, with a NPV and PPV of 92% and 28%, respectively (odds ratio of 4.4). Therefore, in both newly diagnosed and relapsed or refractory AML, this classifier improves the overall response rate by approximately 50% while maintaining a high NPV, and significantly improves patient overall survival. The two-gene classifier was also validated by qPCR in thirty AML samples from the same clinical study demonstrating a negative predictive value (NPV) and positive predictive value (PPV) of 81% and 50%, respectively (odds ratio of 4.3). These data indicate that a simple two-gene expression assay may have utility in diagnosing a population of AML patients who are more likely to respond to tipifarnib.

Liver cancer prediction system for early detection and control method thereof

The present invention relates to a liver cancer prediction system for early detection and control method thereof, which can perform hierarchical classification relating to a risk group for hepatocellular carcinoma, through an estimation of the incidence rate for the hepatocellular carcinoma and a relative risk of the incidence of hepatocellular carcinoma, both of which are found on an individual basis. General information on a patient, information depending on an ultrasonic test performed, clinical information including information on findings upon a first registration of a patient and information on findings upon a diagnosis of liver cancer, and information on a risk group, are stored in a database. A regression count which is an attributable ratio corresponding to each of risk factors is calculated based on the clinical information and risk group information stored in the database. An odds ratio of the incidence of liver cancer is measured by calculating risk probability of the incidence of liver cancer through a given operation process using the calculated regression count. It is thus possible to prevent the incidence of liver cancer per person depending on prediction of the incidence of liver cancer. Also hierarchical classification relating to a risk group for hepatocellular carcinomas is performed through the incidence rate for hepatocellular carcinoma and a relative risk of the incidence of liver cancer that are calculated on an individual basis.

Method for identifying and employing high risk genomic markers for the prediction of specific diseases

InactiveUS20140344272A1Facilitates genetic marker classification of disease riskEnhanced discovery procedureDigital data processing detailsRelational databasesStandard formSelection criterion
A reorganization of genomic data into a simpler standard form leads to more transparent data analyses. The customary selection practice that focuses on high odds ratios loci is shown to be biased, reflecting quality of presently reported risk loci for T2D. A selection criterion, based on Shannon information theory, brings clarity to this issue and provides a rational and optimal basis for selecting potential risk loci. This is used to determine an optimal disease classifier. Within the framework of the FUSION database this leads to a relatively successful degree of T2D prediction and nearly an order of magnitude more effective in detecting T2D. Chromosome 7 is strongly associated with T2D. A hypothesis of this study is that the genomic disease signal is possibly weak, and instead of focusing on individual loci a collection of loci contribute to a composite Score, which functions as the determinant of disease or its absence.
