NCT02461381

Brief Summary

This study aimed to estimate sensitivities and specificities of diabetic cardiovascular autonomic neuropathy (DCAN) diagnostic tests using the Bayesian approach without a gold standard in another independence dataset.The reference the values for the short-term HRV were calculated in the investigators' previous study (including 371 healthy subjects). This study dataset contained 200 diabetic patients who completed both the short-term HRV test and Ewing's test. Simultaneous inferences about the population prevalence and the performance of each diagnostic test were possible using the Bayesian approach without a gold standard.

Outcome Measures

Primary Outcomes (2)

  • Diabetic cardiovascular autonomic function evaluate by short-term heart rate variability test

    Both short-term heart rate variability and Ewing's test measure diabetic cardiovascular autonomic function

    participants will be measured for the duration of outpatient stay, an expected average of two days

  • Diabetic cardiovascular autonomic function evaluate by Ewing's test

    Both short-term heart rate variability and Ewing's test measure cardiovascular autonomic function

    participants will be measured for the duration of outpatient stay, an expected average of two days
