About this study
Three-dimensional (3D) printed anatomic models are increasingly being developed for medical education. The investigators sought to compare the efficacy of a 3D printed model of the mediastinum as a study tool with standard textbooks for teaching medical trainees thoracic anatomy.
Participants were randomly assigned to either a lecture using a standard anatomy textbook or the same lecture along with a 3D printed model of the mediastinum. Participants took a timed pre-test and post-test, identifying 12 mediastinal structures on a prosected human cadaver. Independent and dependent t-tests were used to compare individual and group improvements respectively. A subjective assessment was also performed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
3D Mediastinum ModelOther
The 3D model cohort was provided with an additional 10-minute interactive lecture reviewing the same focused mediastinal anatomical structures using the 3D model.
| Study group | Role | What they receive |
|---|---|---|
| Textbook Cohort | No intervention | Trainees underwent a 10-minute lecture using two-dimensional (2D) images of the mediastinum selected from standard textbook resources. The lecture carefully reviewed the mediastinal anatomy reflected in the prosected cadaver and provided a variety of 2D axial, coronal, and sagittal images. |

What is being measured
The primary outcome is the main question the study is designed to answer.
Improvement from pre-test to post-test
Participants took a same-day timed pre-test and post-test, identifying 12 mediastinal structures on a prosected human cadaver. Independent and dependent t-tests were used to compare individual and group improvements respectively
Measured: Up to 1 year
Secondary outcomes (1)
Subjective Evaluation
Medical trainees were given a subjective assessment on the perceived benefit of the model
Measured: Up to 1 year

Questions about this trial
What is this clinical trial studying?
A study testing 3D Mediastinum Model in people with Anatomy Teaching Methods, run by Stanford University at 1 site in United States.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Sep 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 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?
Improvement from pre-test to post-test (time frame: Up to 1 year). 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 10 Sep 2021.
