Current landscape of type 1 diabetes mellitus-related interventional clinical trials registered on ClinicalTrials.gov: a cross-sectional study.

T1DM-related interventional clinical trials registered in ClinicalTrials.gov were dominated by small single-center studies. Most trials lacked the availability of results and their respective publications. Large multicenter interventional clinical trials on T1DM are needed, and more attention should be paid to improve the publication and dissemination of clinical trials results.
