NCT ID NCT02080741
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether people with type 1 or type 2 diabetes who have a 'Type A' (impatient, proactive) or 'Type B' (calm, slow) personality show different genetic markers linked to inflammation and stress. Researchers planned to collect blood samples and have participants complete questionnaires and a psychology interview. The study was terminated early, so results are limited.
