Description

<p>Objective: Missing high evidence-level articles during a literature search inhibits the use of information useful for research programs and reviews. Checking the core journals included in the search results serves as a guide to determining the search’s appropriateness. This study specifically researched core journals on peptic ulcer remedies to verify the quality of articles included therein.</p><p>Method: We searched for core journals on peptic ulcer remedies using Bradford’s law. To evaluate the quality of the articles included in the core journals, we examined the implementation rates of RCTs and the double-blind method.</p><p>Results: We were able to verify Bradford curves from the extracted articles. Each journal group approximated the theoretical values based on proportional expressions. 2,164 occurrences of omeprazole, 1,109 occurrences of ranitidine, and 917 occurrences of cimetidine were extracted from the database. Two of the core journals were about omeprazole, three about ranitidine, and five about cimetidine. All core journals were specialty journals on the digestive system, except for The Lancet. The implementation rates of RCT and double-blind method comparison tests for the core journals tended to be higher than other journal groups.</p><p>Conclusion: Quantitative processing of the clinical papers on each drug enabled us to identify appropriate core journals. Because the quality of this journal group tended to be higher than that of other groups, the search quality can be assured by checking the core journals included in search results.</p>
