About this study
Official title: Evaluating Length and Depth Estimation Accuracy
The objective of the study is to measure accurateness of length and depth estimation of laypersons and health-care providers.
Read the detailed description
The study hypothesis is that both laypersons and health-care providers will have difficulty estimating length and depth. The study will enroll 100 laypersons and 100 health-care providers. The participants will be asked to draw a 5cm line without assistance an estimate 5cm depth to measure accurateness of length and depth estimation.

Questions about this trial
What is this clinical trial studying?
A study testing Laypersons and Health-Care Providers in people with Cardiopulmonary Resuscitation, run by Seoul National University Hospital at 1 site in South Korea.
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 2 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 17 Jan 2025. 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 South Korea. 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?
Contact STEPHEN GW LEE, MD, MA (82-10-5124-8415, LEESTEPHENGYUNGWON@GMAIL.COM), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Depth estimation (time frame: Measurement immediately after registration on the day of arrival at the study site (protocol will take less than 5 minutes to complete)). 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 NCT06552299, 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 17 Jan 2025.
