CM. A brief note on Systematic Reviews and Meta-analysis. A strategy to reduce wasted biomedical research

Professor Arturo Martí-Carvajal, from the Faculty of Health Sciences, University of Carabobo, Venezuela, is a long-standing academic with a distinguished career in clinical practice, teaching, and clinical research in Venezuela as well as in other important universities abroad. Here, we asked Dr. Marti-Carvajal, to give us a glimpse of systematic reviews and meta-analysis, both of which comprise fundamental tools to assess epidemiological study designs of a mass of research data, such as the tons of information being produced every week on Covid-19. The reader could then learn the basic features of meta-analysis, for instance, to explore some of the works presented here in our Portal, both at CientMed and the Covid-19 section. To get an idea of the so many publications on Covid-19, by August 28th, 2020, a study in Scientometrics reported, «23,634 unique documents…were published between January 1 and June 30, 2020.» With respect to the number of a meta-analysis of Covid-19, PubMed reports 773 articles as of September 29, 2020. The need is there to get a handle and grasp this epidemiological tool. We thought that the best guide for this endeavor would be no other than Professor Marti-Carvajal.

    Expreso mi gratitud al Dr. Rangel-Aldao, por la invitación a escribir esta publicación.

    La etimología de la palabra «portal» significa «»primera pieza de la casa donde se recibe a las visitas»». ( Gracias a la inicitiva del Dr. Rangel-Aldao es posible entrar de visita a la Academia Nacional de Medicina, a través de CientMed; también, obra suya. Manifiesto mis felicitaciones. Cuando la pobreza de sentido reina en estos malvados hogaños tiempos venezolanos; obras como estas entusiasman a la comunidad científica venezolana.

    1. Academia Nacional de Medicina

      Gracias, Dr. Martí-Carvajal por sus generosos comentarios respecto a esta invitación nuestra de un artículo suyo, que responde a una necesidad en Venezuela de tener una guía amigable para abordar y entender decenas de metanálisis sobre ensayos clínicos de medicamentos y vacunas contra el Covid-19.
