When conditional logistic regression is based on the exact conditional distribution for inference, the intercept is eliminated. This becomes a problem when the predicted probability is a key issue for binary discrimination. This report details a new algorithm for risk score instead of predicted probability for strati5ed data in binary discrimination. From the statistical point of view, data par...

This paper proposes an efficient three fold stratified SIFT matching for iris recognition. The objective is to filter wrongly paired conventional SIFT matches. In Strata I, the keypoints from gallery and probe iris images are paired using traditional SIFT approach. Due to high image similarity at different regions of iris there may be some impairments. These are detected and filtered by finding...

BACKGROUND Initiation of combination antiretroviral therapy (ART) results in higher total CD4 cell counts, a surrogate for immune reconstitution. Whether the baseline CD4 cell count affects reconstitution of immune cell subsets has not been well characterized. METHODS Using data from 978 patients (621 with comprehensive immunological assessments) from the AIDS [Acquired Immunodeficiency Syndr...

Population stratification remains an important issue in case-control studies of disease-marker association, even within populations considered to be genetically homogeneous. Campbell et al. (Nature Genetics 2005;37:868-872) illustrated this by showing that stratification induced a spurious association between the lactase gene (LCT) and tall/short status in a European American sample. Furthermor...

Objectives The Iowa Healthy and Active Minds Study is a four-arm randomised controlled trial of a visual processing speed training programme (Road Tour). This article presents the preplanned interim results immediately after training (6-8 weeks post-randomisation) for the primary outcome. Design Within two age strata (50-64 vs ≥65), 681 men and women attending general internal and family medic...

The roof control of a fully mechanized mining face has significant impact on coal extraction. Therefore, information about strata behavior and differentiated measures for abnormal roofs are needed. In the present research, we used ground pressure theory to calculate interval first periodic weighting working faces 11113, 11213, 11313 in Panbei mine. maximum support resistance required by three w...

Background: Periodontal disease and diabetes share a two way relationship because of common pathways of disease progression. Aims & Objective: Extensive study on various population worldwide were carried out but there is a limited data for Indian population, Hence, the present study was done to evaluate the prevalence and severity of periodontitis in type 2 diabetes mellitus of Bareilly region ...
