In 1996-1997, the AIDS Clinical Trial Group 320 study randomized 1156 HIV-infected U.S. patients to combination antiretroviral therapy (ART) or highly active ART with equal probability. Ninety-six patients incurred AIDS or died, 51 (4 per cent) ...

Non-inferiority tests for clustered matched-pair data.
28 May 2009 
Non-inferiority tests for matched-pair data where pairs are mutually independent may not be appropriate when pairs are clustered. The tests may require an adjustment to account for the correlation within a cluster. We consider the adjusted score and ...

A multivariate CAR model for improving the estimation of relative risks.
28 May 2009 Disease mapping studies have been widely performed at univariate level, that is considering only one disease in the estimated models. Nonetheless, simultaneous modelling of different diseases can be a valuable tool both from the epidemiological and ...

Measures of between-cluster variability in cluster randomized trials with binary outcomes.
28 May 2009 Cluster randomized trials (CRTs) are increasingly used to evaluate the effectiveness of health-care interventions. A key feature of CRTs is that the observations on individuals within clusters are correlated as a result of between-cluster ...

28 May 2009 Recent changes in individual units are often of interest when monitoring and assessing the performance of healthcare providers. We consider three high profile examples: (a) annual teenage pregnancy rates in English local authorities, (b) quarterly ...

Blinded assessment of treatment effects utilizing information about the randomization block length.
28 May 2009 It is essential for the integrity of double-blind clinical trials that during the study course the individual treatment allocations of the patients as well as the treatment effect remain unknown to any involved person. Recently, methods have been ...

28 May 2009 Increased survival is a common goal of cancer clinical trials. Owing to the long periods of observation and follow-up to assess patient survival outcome, it is difficult to use outcome-adaptive randomization in these trials. In practice, often ...

Joint analysis of prevalence and incidence data using conditional likelihood.
18 May 2009 Disease prevalence is the combined result of duration, disease incidence, case fatality, and other mortality. If information is available on all these factors, and on fixed covariates such as genotypes, prevalence information can be utilized in the ...

Classification of schizophrenia with spectro-temporo-spatial MEG patterns in working memory.
18 May 2009 OBJECTIVE: To investigate whether temporo-spatial patterns of brain oscillations extracted from multichannel magnetoencephalogram (MEG) recordings in a working memory task can be used successfully as a biometric marker to discriminate between ...

Personal authentication using hand vein triangulation and knuckle shape.
13 May 2009 This paper presents a new approach to authenticate individuals using triangulation of hand vein images and simultaneous extraction of knuckle shape information. The proposed method is fully automated and employs palm dorsal hand vein images acquired ...
