Study population: Diabetic patients with inclusion and exclusion criteria were recruited from healthy examination centres to assess cardiovascular autonomic function using both the short-term heart rate variability and Ewing's tests.
Who may be able to join
- Survey diabetic participants with undiagnosed CAN, aged 30-90 years, were included in this study.
Who cannot join
- Some subjects were excluded from the study to eliminate potential confounding factors that may have influenced their CA function. Briefly, the exclusion criteria were as follows:

About this study
Official title: Bayesian Estimation of Diagnostic Performance of Short-term Heart Rate Variability for Diabetic Cardiovascular Autonomic Neuropathy in the Absence of a Gold Standard
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.
Read the detailed description
The CAN prevalence is rapidly growing in all populations worldwide. No document has been reported diagnostic performance of short-term heart rate variability (HRV) for diabetic cardiovascular autonomic neuropathy (DCAN) in the Chinese population. This study aimed to estimate sensitivities and specificities of DCAN diagnostic tests using the Bayesian approach, in the absence of 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 subjects 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.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetic Cardiovascular Autonomic Neuropathy (DCAN), run by Shanghai Tongji Hospital, Tongji University School of Medicine at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diabetic cardiovascular autonomic function evaluate by short-term heart rate variability test (time frame: participants will be measured for the duration of outpatient stay, an expected average of two days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02461381, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jan 2021.
