OBJECTIVES: To evaluate the clinical characteristics among hypertension patients with diabetes in Shanghai, China. METHODS: Data from a population-based database in Minhang area including 180,806 hypertensive patients were examined. All hypertension cases were collected through 12 community health centers and then enrolled in the electronic Health Records (eHR) system.
