The goals of this project were to compare research integrity content in Instructions for Authors in ICMJE member journals with those in the English- and Japanese-language journals of the Japanese Association of Medical Sciences (JAMS). Therefore, this dataset contents include the following three categories: 1) journals' background information, 2) description numbers of research integrity topics, and 3) journal numbers that required ICMJE description forms in ICMJE member journals, English- and Japanese-language journals.
