What is being measured
The primary outcome is the main question the study is designed to answer.
accuracy of clinic-based weight measurement
Participants will be asked to weigh individuals who they have been told are completing either the treatment or control condition of a weight loss trial (individuals will actually be paid actors playing the role of a study participant). Participants will weigh individuals on calibrated balance-beam scales, and the discrepancy between weights recorded when individuals are thought to be a treatment or control participant will be calculated, which is the primary outcome for this study.

Primary outcome
accuracy of clinic-based weight measurement
Time frame: baseline
Participants will be asked to weigh individuals who they have been told are completing either the treatment or control condition of a weight loss trial (individuals will actually be paid actors playing the role of a study participant). Participants will weigh individuals on calibrated balance-beam scales, and the discrepancy between weights recorded when individuals are thought to be a treatment or control participant will be calculated, which is the primary outcome for this study.
Results and safety
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

Questions about this trial
What is this clinical trial studying?
An observational study of Accuracy of Clinic-based Weight Measurements, run by University of Alabama at Birmingham at 1 site in United States.
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: finished, as of the sponsor's last update on 17 Sep 2019. 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 United States. 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?
accuracy of clinic-based weight measurement (time frame: baseline). 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 17 Sep 2019; AzTrials last refreshed its copy on 30 Oct 2026.
