    (2018) Alqaydi, Ahlam R; Naser-ud-Din, Shazia; Athanasiou, Athanasios E
    Background/Objective: This study was conducted to explore authorship characteristics and publication trends of all orthodontic randomized controlled trials (RCTs), systematic reviews (SRs), and meta-analyses (MAs) published in non-orthodontic journals with impact factor (IF). Materials and methods: Appropriate research strategies were developed to search for all articles published until December 2015, without restrictions regarding language or publication status. The initial search generated 4524 results, but after application of the inclusion criteria, the final number of articles was reduced to 274 (SRs: 152; MAs: 36; and RCTs: 86). Various authorship characteristics were recorded for each article. Frequency distributions for all parameters were explored with Pearson chi-square for independence at the 0.05 level of significance. Results: More than half of the included publications were SRs (55.5 per cent), followed by RCTs (31.4 per cent) and MAs (13.1 per cent); one hundred seventy-eight (65 per cent) appeared in dental journals and 96 (35 per cent) were published in non-dental journals. The last decade was significantly more productive than the period before 2006, with 236 (86.1 per cent) articles published between 2006 and 2015. European countries produced 51.5 per cent of the total number of publications, followed by Asia (18.6 per cent) and North America (USA and Canada; 16.8 per cent). Limitations: Studies published in journals without IF were not included. Conclusions/Implications: Level-1 evidence orthodontic literature published in non-orthodontic journals has significantly increased during 2006–15. This indicates a larger interest of other specialty journals in orthodontic related studies and a trend for orthodontic authors to publish their work in journals with impact in broader fields of dentistry and medicine.
