Accuracy and cut-off point selection in three-class classification problems using a generalization of the Youden index
(2010)We study properties of the index J(3), defined as the accuracy, or the maximum correct classification, for a given three class classification problem Specifically, using J(3) one can assess the discrimination between the ... -
An approach for modelling multiple correlated outcomes in a network of interventions using odds ratios
(2014)A multivariate meta-analysis of two or more correlated outcomes is expected to improve precision compared with a series of independent, univariate meta-analyses especially when there are studies reporting some but not all ... -
A Collaborative Biomedical Image-Mining Framework: Application on the Image Analysis of Microscopic Kidney Biopsies
(2013)The analysis and characterization of biomedical image data is a complex procedure involving several processing phases, such as data acquisition, preprocessing, segmentation, feature extraction, and classification. The ... -
A comparison of tests for restricted orderings in the three-class case
(2009)A variety of methods for comparing three distributions have been proposed in the literature. These methods assess the same null hypothesis of equal distributions but differ in the alternative hypothesis they consider. The ... -
Considerations on what constitutes a 'qualified statistician' in regulatory guidelines
(2012)International regulatory guidelines require that a qualified statistician takes responsibility for the statistical aspects of a clinical trial used for drug licensing. No consensus on what constitutes a qualified statistician ... -
Emergency Fall Incidents Detection in Assisted Living Environments Utilizing Motion, Sound, and Visual Perceptual Components
(2011)This paper presents the implementation details of a patient status awareness enabling human activity interpretation and emergency detection in cases, where the personal health is threatened like elder falls or patient ... -
Enabling Location Privacy and Medical Data Encryption in Patient Telemonitoring Systems
(2009)Patient telemonitoring systems (PTS) deal with the acquisition, processing, and secure transmission of a patient's physiological and physical parameters to a remote location, where expert medical knowledge is available. ... -
Enhancing classification accuracy utilizing globules and dots features in digital dermoscopy
(2015)The interest in image dermoscopy has been significantly increased recently and skin lesion images are nowadays routinely acquired for a number of skin disorders. An important finding in the assessment of a skin lesion ... -
GRISSOM Platform: Enabling Distributed Processing and Management of Biological Data Through Fusion of Grid and Web Technologies

HELOW: A program for testing extreme homogeneity in meta-analysis
(2014)Meta-analysis aims to synthesize results from different studies. Although, in a meta-analysis the presence of large between-study heterogeneity is routinely evaluated, in some instances is also important to probe whether ... -
Implementation and Integration of Regional Health Care Data Networks in the Hellenic National Health Service
(2002)Background: Modern health care is provided with close cooperation among many different institutions and professionals, using their specialized expertise in a common effort to deliver best-quality and, at the same time, ... -
A medical ontology for intelligent web-based skin lesions image retrieval
(2011)Researchers have applied increasing efforts towards providing formal computational frameworks to consolidate the plethora of concepts and relations used in the medical domain. In the domain of skin related diseases, the ... -
METRADISC-XL: A program for meta-analysis of multidimensional ranked discovery oriented datasets including microarrays
(2012)A comprehensive software for performing meta-analysis of ranked discovery oriented datasets, such as those derived from microarrays or other high throughput technologies, and for testing between-study heterogeneity for ... -
A novel tool for segmenting 3D medical images based on generalized cylinders and active surfaces
(2013)Three-dimensional (3D) medical imaging has been incorporated in routine clinical practice, since the required infrastructure has become increasingly affordable. New algorithms and applications are needed to serve the ... -
On the covariance of two correlated log-odds ratios
(2012)In many applications two correlated estimates of an effect size need to be considered simultaneously to be combined or compared. Apparently, there is a need for calculating their covariance, which however requires access ... -
Overview of Advanced Computer Vision Systems for Skin Lesions Characterization
(2009)During the last years, computer-vision-based diagnosis systems have been used in several hospitals and dermatology clinics, aiming mostly at the early detection of skin cancer, and more specifically, the recognition of ... -
Strengths and Weaknesses of 1.5T and 3T MRS Data in Brain Glioma Classification
(2011)Although magnetic resonance spectroscopy (MRS) methods of 1.5Tesla (T) and 3T have been widely applied during the last decade for noninvasive diagnostic purposes, only a few studies have been reported on the value of the ... -
Support Vectors Machine-based identification of heart valve diseases using heart sounds
(2009)Taking into account that heart auscultation remains the dominant method for heart examination in the small health centers of the rural areas and generally in primary healthcare set-ups, the enhancement of this technique ...
