INTRODUCTION: The database http: //cedd.saglik-network.org (CEDD-NET) has been operating since 2013 in Turkey. All pediatric endocrinologists can propose projects to this network. The aim of our study was to determine the impact of CEDD-NET on the transformation of multicenter studies into scientific publications and assess the academic characteristics of the studies that have been transcribed into publication. METHODS: All the studies that were opened to patient admission on the website between August 26, 2013 and March 1, 2021 were reviewed. Results: A total of 30 studies were accepted and opened for data entry. The median data collection period was 12 (1.5-24) months, while the median number of researchers participated was 23 (3-180), the median number of cases was 120 (26-192). The average cost was $2113 (1370-3118). Out of 30 studies, data entry was completed for 27. Sixteen publications were produced from 14 studies, 13 ot them have not published yet. The median time from the end of data entry to publication of the study was 686 (168-1608) days. While the median impact factor of the journals in which the studies were published was 1.803 (1.278-5.399), the median number of citations was 6.5 (0-49), and cited by 99 times in Web of Science indexed journals in total. DISCUSSION AND CONCLUSION: CEDD-NET appears to be productive and effective as all the publications are of high quality that have been published in the Q1-Q2 categories. This study demonstrated the benefits and necessity of establishing nationwide databases, even covering more than one country, in specialized branches, such as pediatric endocrinology where rare diseases are of concern.
