Integrin, alpha 2 gene C807T polymorphism and risk of ischemic stroke: A meta-analysis
Nikolopoulos, Georgios K.; Tsantes, Argirio E.; Bagos, Pantelis G.; Travlou, Anthi S.; Vaiopoulos, G. (2007)Introduction: Platelet adhesion to fibrillar collagen via the membrane glycoprotein (GP) Ia/IIa (α2β1), is a crucial event in the pathogenesis of arterial occlusive disorders. The C807T single nucleotide polymorphism of ...

Interleukin gene polymorphisms and susceptibility to HIV-1 infection: a meta-analysis
Nikolopoulos, Georgios K.; Tsiara, Chrissa G.; Dimou, Niki L.; Pantavou, Katerina G.; Bagos, Pantelis G.; Mensah, Benedicta; Talias, Michael; Braliou, Georgia G.; Paraskeva, Dimitra; Bonovas, Stefanos; Hatzakis, Angelos (2018)Some subjects are repeatedly exposed to human immunodeficiency virus (HIV), yet they remain uninfected. This suggests the existence of host-resistance mechanisms. The current study synthesizes the evidence regarding the ...

Lack of association between the platelet glycoprotein Ia C807T gene polymorphism and coronary artery disease: A meta-analysis
Tsantes, Argirio E.; Nikolopoulos, Georgios K.; Bagos, Pantelis G.; Vaiopoulos, G.; Travlou, Anthi S. (2007)Background: The platelet-collagen receptor, glycoprotein (GP) la/lla plays a crucial role in the adhesion of platelets to fibrillar collagen, an event contributing to the pathogenesis of thrombosis. The C807T polymorphism ...

Meta-analysis of family-based and case-control genetic association studies that use the same cases
Bagos, Pantelis G.; Dimou, Niki L.; Liakopoulos, Theodore D.; Nikolopoulos, Georgios K. (2011)In many cases in genetic epidemiology, the investigators in an effort to control for different sources of confounding and simultaneously to increase the power perform a family-based and a population-based case-control study ...

A method for meta-analysis of case-control genetic association studies using logistic regression
Bagos, Pantelis G.; Nikolopoulos, Georgios K. (2007)We propose here a simple and robust approach for meta-analysis of molecular association studies. Making use of the binary structure of the data, and by treating the genotypes as independent variables in a logistic regression, ...

Mixed-effects poisson regression models for meta-analysis of follow-up studies with constant or varying durations
Bagos, Pantelis G.; Nikolopoulos, Georgios K. (2009)We present a framework for meta-analysis of follow-up studies with constant or varying duration using the binary nature of the data directly. We use a generalized linear mixed model framework with the Poisson likelihood ...

No evidence for association of CTLA-4 gene polymorphisms with the risk of developing multiple sclerosis: A meta-analysis
Bagos, Pantelis G.; Karnaouri, Anthi C.; Nikolopoulos, Georgios K.; Hamodrakas, Stavros J. (2007)We conducted a meta-analysis concerning the association of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) gene polymorphisms with the risk of developing multiple sclerosis (MS). We identified 18 eligible studies ...

Plasminogen activator inhibitor-1 4G/5G polymorphism and risk of ischemic stroke: A meta-analysis
Tsantes, Argirio E.; Nikolopoulos, Georgios K.; Bagos, Pantelis G.; Tsiara, Chrissa G.; Kapsimali, Violetta; Travlou, Anthi S.; Vaiopoulos, G. (2007)This study investigated the hypothesis that the insertion/deletion (4G/5G) polymorphism of the plasminogen activator inhibitor type-1 gene affects the risk for ischemic stroke, since results concerning this association ...

Use of Fibrates and Cancer Risk: A Systematic Review and Meta-Analysis of 17 Long-Term Randomized Placebo-Controlled Trials
Bonovas, Stefanos; Nikolopoulos, Georgios K.; Bagos, Pantelis G. (2012)Background: Fibrates comprise a class of well-established antilipidemic agents that significantly reduce cardiovascular events. Given the concerns of cancer with fibrate therapy, we undertook a systematic review and ...
