Background/Aims: Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. Patients and Methods: An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. Results: A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1 st 5-year period (2003-2007) to 330 in the 2 nd period (2008-2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. Conclusion: In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals.
