Objective: To determine the extent to which nephrology journals recommend and require reporting guideline adherence and clinical trial registration. Background: Despite a rising disease burden, research published on chronic kidney disease (CKD) and the field of nephrology has failed to keep pace and is limited. To improve the quality of research in the field of nephrology, reporting guidelines have been developed to minimize such deficits in research quality. However, the extent to which nephrology journals require and use reporting guidelines in addition to clinical trial registration is unknown. Methods: Sixty-two Nephrology journals were selected through the 2021 Scopus CiteScore tool. Each journal's Instructions for Authors was assessed to determine endorsement of study design-specific reporting guidelines or clinical trial registration. Researchers used R (version 4.2.1) and RStudio to create data summaries of descriptive statistics for nephrology journal reporting guidelines. Results: Clinical trial registration was required by 52% (32/62) of nephrology journals within our sample. The reporting guideline for clinical trials, CONSORT, was required by 17.74% (11/62) of journals. The EQUATOR Network was mentioned by 46.77% (29/62) of journals, while 9.67% (6/62) failed to mention the ICMJE. The reporting guideline for systematic review, PRISMA, was only required by 12.90% (8/62) of journals. When contacting journal editors, 9.67% (6/62) responded and 4.83% (3/62) provided clarifying information. Conclusions: Reporting guidelines and clinical trial registration are suboptimally required and recommended by nephrology journals. Their adoption may decrease bias and increase research quality. Thus, nephrology journals should consider a more complete endorsement of these safeguards. Graphical abstract: (Figure presented.).
