Recuperación e Identificación de Ensayos Clínicos Aleatorizados para Revisiones Sistemáticas: Búsqueda Manual
Studies that appear in electronic databases are just the “iceberg’s top”. Only a few of the enormous amount received by journal editors are selected to be published in scientific publications. Journals which have higher impact
factor receive thousands of them, which mostly rejected even without any revision from editors. After that, authors use to apply to another journal with
lower impact factor and so on, hoping to be finally published. Hand searching was designed to recover some of these studies; perhaps it could be valuable and unknown information, not considered in a database or maybe
available only in printed form, which is what happens with the oldest ones.
