About this study
Official title: Withings Study to Analyze the Accuracy of Pulse Wave Velocity Measurement With Bathroom Scales
The aim of this study is to evaluate the diagnostic performance of Withings bathroom scales WBS08 and WBS12 to measure PWV (Pulse Wave Velocity).
Read the detailed description
Patients likely to have a high PWV (having hypertension, sleep apnea or chronic obstructive pulmonary disease) are included in hospitals. Each patient will have his PWV measured with Withings WBS08 and WBS12 and its reference the SphygmoCor CvMS.
- Conditions
- Vascular Stiffness
- Being tested
- PWV measurement
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PWV measurementOther
Patient will have its PWV measured with the reference (the SphygmoCor) and by stepping on Withings bathroom scales WBS08 and WBS12.
| Study group | Role | What they receive |
|---|---|---|
| Hypertension | Hypertensive patient Receives: Other: PWV measurement | |
| Sleep apnea or COPD | Patient having sleep apnea or COPD (Chronic obstructive pulmonary disease) Receives: Other: PWV measurement |
What is being measured
The primary outcome is the main question the study is designed to answer.
PWV measurement bias
Difference between the PWV measured and the PWV reference (m.s-1)
Measured: 1 year
PWV measurement deviation
The standard deviation of the difference between the PWV measured and the PWV reference (m.s-1)
Measured: 1 year
Secondary outcomes (1)

Questions about this trial
What is this clinical trial studying?
An observational study of Vascular Stiffness, run by Withings at 2 sites in France.
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 6 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 18 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. 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?
This study is still under way. Results are not available in the source record yet.
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?
PWV measurement bias (time frame: 1 year). 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?
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 18 Feb 2026.
