Revisiones sistemáticas más inclusivas: El valor de las bases regionales y abiertas en la investigación latinoamericana. Una revisión crítica

The article critically analyzes the impact of requiring the exclusive use of articles indexed in Scopus/Web of Science for systematic reviews carried out by postgraduate students in Latin America. Through a descriptive-documentary study, 10 systematic review articles published in Scopus between 2024 and 2025 were examined, identifying the databases and search engines used. The findings show that although Scopus was the most recurrent database (9 out of 10 studies), the reviews were not limited to it, as they also included PubMed, Web of Science, Cochrane, Embase, CINAHL, SciELO, Dialnet, Redalyc, Google Scholar, among others. This reflects a trend toward the diversification of sources in order to reduce publication bias, incorporate regional evidence, and ensure comprehensiveness. It was also observed that the choice of databases depends on the thematic area: in health, biomedical databases (PubMed, Embase, CINAHL) prevail, while in social sciences and education, sources such as ERIC, PsycINFO, Redalyc, or Dialnet are prioritized. Likewise, Google Scholar appears as a complementary tool to locate gray literature.
