The Open Epidemiology Journal is an Open Access online journal, which research articles, reviews/mini-reviews, letters and guest edited single topic issues in all areas of epidemiology related to preventive medicine and public health.
The Open Epidemiology Journal, a peer reviewed journal, is an important and reliable source of current information on developments in the field. The emphasis will be on publishing quality articles rapidly and freely available worldwide.
Statistical frequentist techniques are sometimes misinterpreted or misused, while Bayesian techniques seem to present several practical advantages, such as accommodating small sample sizes, unobserved variables along with measurement errors and Incorporating information from previous studies. The primary objective of this study was to evaluate the association between waterpipe dependence and chronic obstructive pulmonary disease (COPD), by comparing frequentist and Bayesian methods’ results.
It is a multicenter case-control study, comparing a group of COPD patients with a control group. COPD diagnosis was held after clinical and paraclinical testing, while a standardized questionnaire was used to evaluate smoking history. Both frequentist and Bayesian analyses were performed.
Although carried out on the same dataset, the results quantitatively differed between the frequentist and Bayesian analysis. Whenever the frequentist results were clear cut such as in case of cigarette smoking association with COPD, performing the MCMC method helped to increase the accuracy of the results, but did not change the direction of hypothesis acceptance, except in doubtful cases. When the frequentist p-value was ≤0.100, such as in case of smoking more than 15 waterpipe-years, the MCMC method improved deciding between the null and alternative hypothesis.
The Bayesian approach may have advantages over the frequentist one, particularly in case of a low power of the frequentist analysis, due to low sample size or sparse data; the use of informative priors might be particularly useful in narrowing credible interval and precising the choice between the null and alternative hypothesis. In case of borderline frequentist results, the MCMC method may be more conservative, particularly without priors. However, in case of large sample sizes, using frequentist methods is preferred.

The Open Epidemiology Journal is an Open Access online journal, which publishes research articles, reviews, letters, case reports and guest-edited single topic issues in all areas of epidemiology. Bentham Open ensures speedy peer review process and accepted papers are published within 2 weeks of final acceptance.
The Open Epidemiology Journal is committed to ensuring high quality of research published. We believe that a dedicated and committed team of editors and reviewers make it possible to ensure the quality of the research papers. The overall standing of a journal is in a way, reflective of the quality of its Editor(s) and Editorial Board and its members.
The Open Epidemiology Journal is seeking energetic and qualified researchers to join its editorial board team as Editorial Board Members or reviewers.
The essential criteria to become Editorial Board Members of The Open Epidemiology Journal are as follows:

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines.". —Daniel Pesut. (Indiana University School of Nursing, USA).
"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor.". —Jacques Descotes. (Centre Antipoison-Centre de Pharmacovigilance, France).
"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community.". —Patrice Talaga. (UCB S.A., Belgium).
"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information.". —Jeffrey M. Weinberg. (St. Luke's-Roosevelt Hospital Center, USA).
"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals.". —Debomoy K. Lahiri. (Indiana University School of Medicine, USA).
"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities.". —Robert Looney. (Naval Postgraduate School, USA).
"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets.". —Richard Reithinger. (Westat, USA).
"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers.". —J. Ferwerda. (University of Oxford, UK).
"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content.". —Sean L. Kitson. (Almac Sciences, Northern Ireland).
"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area.". —Hubert Wolterbeek. (Delft University of Technology, The Netherlands).
"The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements.". —Alessandro Laviano. (Sapienza - University of Rome, Italy).
"Open access journals are very useful for all scientists as they can have quick information in the different fields of science.". —Philippe Hernigou. (Paris University, France).
"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information.". —Fidel Toldrá. (Instituto de Agroquimica y Tecnologia de Alimentos, Spain).
"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas.". —M. Bendandi. (University Clinic of Navarre, Spain).
"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope.". —Peter Chiba. (University of Vienna, Austria).
"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide.". —Jaime Sampaio. (University of Trás-os-Montes e Alto Douro, Portugal).
"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists.". —Eduardo A. Castro. (INIFTA, Argentina).
"Open access journals are freely available online throughout the world, for you to read, download, copy, distribute, and use. The articles published in the open access journals are high quality and cover a wide range of fields.". —Kenji Hashimoto. (Chiba University, Japan).
"Open Access journals offer an innovative and efficient way of publication for academics and professionals in a wide range of disciplines. The papers published are of high quality after rigorous peer review and they are Indexed in: major international databases.
