About this study
A study population with impaired fasting glucose levels, impaired glucose tolerance levels and diabetes (with or without complications) along with healthy patients will be chosen as participants. Their vital signs and their ECG (electrocardiograph) will be recorded during their only visit. Data analysis will be performed using the vital signs parameters. The RR intervals from the ECG will be analyzed by 5 different techniques to determine the best technique that stratifies the subjects the most accurately.
Read the detailed description
The Autonomic Nervous System (ANS) is a fundamental part of the nervous system in the body. And yet, there is no technique to test or measure the health and functioning of a person's autonomic nervous system.This type of study will determine the most accurate methodology to test the autonomic nervous system through heart rate variability (HRV) monitoring and gain vital information to distinguish patient groups in the diabetic population.
There is no gold standard for measuring autonomic dysfunction. Currently the method of power spectral analysis is finding very wide usage. It Is known that power spectral analysis does not discriminate the two subsystems of the ANS well. There are other beat to beat methodologies that have not yet gained traction. The reason for conducting this trial is to take a group of subjects in various stages of impaired fasting glucose, impaired glucose tolerance and diabetes (with and without complications) and determine which methodology stratifies these subjects most accurately.
Our study aims to introduce a new measurement method named the 'Beat to Beat' (BB) method for gauging autonomic dysfunction in patients. The investigators hope to observe that the average beat to beat method (BB) score could help discriminating diabetic patients into the following five distinct groups from the pilot study:
- Normal blood glucose level: - (A blood sugar level less than 140 mg/dL)
- Impaired fasting glucose (IFG): - (A fasting blood sugar level from 100 to 125 mg/dL)
- Impaired glucose tolerance (IGT): - (two-hour glucose levels of 140 to 199 mg per dL
- Diabetes without complications: - (e.g., no neuropathy, no retinopathy or nephropathy)
- Diabetes with complications: - (at least one complication among neuropathy, retinopathy, or nephropathy)
By showing that this measurement bears no relationship to the other four vital signs parameters (heart rate, blood oxygenation, blood pressure, body temperature), it will prove the necessity of this measurement in addition to the four vital signs for distinguishing patient groups among the diabetic population.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Device: ANSiScope PlusOther
Heart rate variability measurement and vital signs monitoring will be performed on all subjects.
| Study group | Role | What they receive |
|---|---|---|
| Impaired Fasting Glucose Individuals | The group contains subjects with various stages of impaired fasting glucose tolerance levels and diabetes (with or without complications). All subjects will be considered in one group since the heart rate variability and vital signs are monitored in a single visit. Receives: Other: Device: ANSiScope Plus |
What is being measured
The primary outcome is the main question the study is designed to answer.
Determination of autonomic dysfunction by subject
The ANSiScope Plus will be used to determine the BB (beat to beat) score through heart rate variability measurements.
Measured: The measurement will happen in a single visit i.e 1 day.
Secondary outcomes (1)
Establish the absence of any relationship of autonomic dysfunction (AD) to any other vital signs parameters.
Investigate the importance of measuring the autonomic dysfunction in the presence of other vital signs measurements (heart rate, body temperature, blood oxygenation and blood pressure)
Measured: The measurement will happen in a single visit i.e 1 day.

What is this clinical trial studying?
An observational study of Diabetes, run by DyAnsys, Inc..
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 9 inclusion and 18 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: withdrawn, as of the sponsor's last update on 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
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 was withdrawn before enrolling participants, so there are no results.
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?
Determination of autonomic dysfunction by subject (time frame: The measurement will happen in a single visit i.e 1 day.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 21 Sep 2026.
