Research methodology consulting

What does it cover?

At OMEDICS we are specialized in review studies: Meta-analysis, systematic review, rapid reviews, review of reviews, narrative review and bibliometric reviews. We also offer support for clinical research. Our service offers support at all stages of the investigation. Which of the following services can we help you with?

Customized research protocol

Careful and standardized way, generally following PRISMA recommendations, of summarizing the evidence on a topic (Evidence Based Medicine – EBM). Systematic literature reviews and meta-analyses are usually the best option if time permits.

Systematic review but with statistical pooling of data. Meta-analysis of clinical trials is the study with the highest level of scientific evidence. Systematic literature reviews and meta-analyses are usually the best option if time permits.

Personal summary of the literature that does not state the methodology used to obtain the information. These are studies with less evidence and a higher risk of bias.

If time is of the essence, a quick or targeted review may be a good option. It is a type of review that synthesizes information in a more efficient way while maintaining transparency. It allows obtaining results in a fast way by answering urgent questions.

Cochrane defines in vivo reviews as “a systematic review that is continually updated, incorporating relevant new evidence as it becomes available.” In vivo reviews offer the advantage of being continuously updated. It also provides researchers with the option to publish passively. What does this mean? Researchers will be able to deposit their studies (of course, that are not published elsewhere) on the Omedics website. In this way, multiple studies on different research topics will be collected, which over time will make it possible to generate more robust publications in the form of reviews and/or meta-analyses. If I upload my work to the Omedics website will it count for anything? Omedics guarantees to the future derivative studies the ISSN necessary for any competition in the health systems.


Part of scientometrics that applies mathematical and statistical methods to all scientific literature and the authors who produce it, with the aim of studying and analyzing scientific activity. It is a very time efficient study. This study is ideal to know where to publish an article and to know the scope of your research. This information can provide competitive knowledge for different institutions, companies and researchers, among others.

Due to the disparate results of the published reviews, this type of review aims to analyze the overall effect on a topic where the number of review publications is high.

Currently there is a lot of competition in the world of research and it is difficult to find a review topic. At Omedics we have an algorithm capable of detecting topics that have not yet been reviewed or improving existing reviews or studies.

Access to scientific studies in the most relevant databases.

We create your personalized database with which you can get the information you want.

Review Manager, SPSS, R commander, Webplotdigitizer: At Omedics we know that statistical analysis of data is the key point in the development of studies.

Analysis of the risk of bias in randomized clinical trials and observational studies as well as the exploration of heterogeneity: Risk of bias by Review Manager and Newcastle-Ottawa Quality Assessment Scale.

Sensitivity analysis, publication bias, regression analysis.

GRADE, the GRADE system is a tool for evaluating the quality of evidence and grading the strength of recommendations in the context of clinical practice guideline development.

We often base our clinical decisions on personal knowledge and experience. Is there room for improvement? Are there other tools for health professionals? Yes, it is evidence-based medical care that integrates clinical expertise with the selection of the best available research evidence. Learning to provide the highest level of high quality evidence is crucial to make the best decision in healthcare, clinical research and health management.

Through systematic reviews of the scientific literature and meta-analysis the highest level of certainty or evidence is achieved that will allow to identify areas and topics for future studies or research, to know the epidemiology of the diseases, the needs of the patients, the most appropriate diagnostic-therapeutic strategy and recommendations on the use of new technologies.

In addition, research projects, publications, conference presentations and curricula are fundamental in a healthcare career. Review papers (meta-analyses, systematic reviews, narrative reviews and bibliometric reviews) are on the rise and are now essential in clinical decision making.

  • Learn how to develop a systematic review and meta-analysis from the formulation of the question to the publication of the article.

The amount of scientific and research studies currently being published is overwhelming even for the most experienced researchers. Scientists and research teams around the world study the most important medical questions and hypotheses, sometimes with diverse and seemingly contradictory results, making decision-making difficult.

Meta-analysis presents a global perspective, I like to say that they “look at everything from above”, and it is a statistical procedure capable of integrating the findings of many independent studies, finding results and general trends that individual studies separately cannot.

A refined methodology is needed to search, select and review the multiple studies published on a specific topic and then combine and analyze the results. Meta-analysis generates research, designing new studies with less risk of bias, adding new variables and generating new hypotheses. This research allows the creation of new clinical guidelines that help health professionals to make decisions.

All studies have biases and it is common to find published systematic reviews and meta-analyses that contain important flaws and poor methodology that may limit the validity of the results. To avoid this, statistical tests are available to account for bias and control for it.

Training in the most evidence-based research

What does it cover?

We often base our clinical decisions on personal experience. Are we really offering the best evidence? Learning to provide the maximum level of high quality evidence in a short time is crucial for making the best decision for the patient, in clinical research and in healthcare management.

Are you part of the health sciences or are you a student and would like to dedicate yourself to research? Do you want to be the leader of your own research? Do you want to increase your reputation? This method contains the formula to become an autonomous researcher just by having access to the Internet.

Is it possible to research and publish autonomously? The answer is yes and it is called meta-analysis.

Meta-analysis consists of using statistical methods on the results of other independent studies to provide more precise estimates than those obtained from the studies included in the review. The number of meta-analysis studies is constantly growing and evolving, and is the most important tool in medical practice.

The interest in publishing is increasing, therefore, being able to accelerate this process will have a great relevance in the scientific community at an international level. Possessing this knowledge will guarantee a competitive advantage in terms of scientific production, which is a fundamental point in a curriculum when assessing any worker in health sciences to obtain a job or improve economic income, among others.
