Interaction of Salivary Proteins and Polyphenols
NCT03501238 · View on ClinicalTrials.gov ↗
Study Summary
Participants will be chosen through an initial sensory test to find high and low-perceivers of astringency. Selected participants will drink a chocolate milk or milk substitute beverage for one week each with washout weeks in between. At the end of each week participants will taste and rate multiple beverages for their astringency and other sensory properties. Participants will provide saliva samples weekly for proteomic analysis and (potentially) analysis of polyphenols. Participants will also be asked to provide a 24 hour dietary recall once per week. Data will be analyzed to determine if there is a relationship between polyphenol exposure, astringency ratings, and salivary protein composition.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03501238
The ClinicalTrials.gov registry entry for NCT03501238 describes a study currently listed as completed. It is categorized as NA, 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 63 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Purdue University, which has 100 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Diet Habit appearing as the primary indexed condition, and to 3 interventions — of which Chocolate Milk 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: NCT03501238 reports 1 study location spanning 1 distinct geographic area — top geographies include Indiana. 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.
