Databases will be maintained in encrypted files, known and accessible only by the research team. Identification and clinical data will be registered in separated databases relatable through random coding. Data will be conserved for five years after the last publication at the head office of the Instituto de Medicina Preventiva from the Faculdade de Medicina of the Universidade de Lisboa, and destroyed after that. Researchers have total responsibility for the confidentiality of the collected data.
The resulting data is property of the Faculdade de Medicina of the Universidade de Lisboa, and this entity has the right to disclose the results (always with integrated data analysis).
