DXA Study of Precision and Reliability
NCT03621306 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of the study is to assess precision of the GE Lunar iDXA, Hologic Horizon W DXA scanner, and the Stratec peripheral quantitative computed tomography (pQCT) scanner. Aim 1: To assess standard deviation (SD) and coefficient of variation (CV) of testing bone mineral, bone geometry, and soft tissues in inanimate objects and adults. Tests on adults will be structured to assess: 1. Within- and between-day variability of testing 2. Within- and between-technician variability of testing 3. Variability due to positioning and post-scan processing 4. Variability due to different DXA scanning equipment Aim 2: To assess the least significant change (LSC) for testing bone mineral and soft tissues in adults. Aim 3: To assess strengths and limitations of DXA and pQCT testing, including sensitivity to movement, rate of re-rescanning, etc. which are crucial components for demonstrating feasibility in grant applications. Aim 4: To construct a database of DXA and pQCT test results and quality control procedures, showing our laboratory's quality control level.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03621306
The ClinicalTrials.gov registry entry for NCT03621306 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 400 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Penn State University, which has 233 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Body Composition appearing as the primary indexed condition, and to 1 intervention — of which DXA and pQCT precision testing is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03621306 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
