Boston Puerto Rican Health Study
NCT03187704 · View on ClinicalTrials.gov ↗
Study Summary
The study is a blinded cross over test of in-home air filtration. Participants will have a window unit air filter (HEPA) installed that will filter for 3 weeks and do sham filtration for another 3 weeks. During the time that the filter is installed in the home a machine that measures particulate air pollution of the type that the filter is designed to remove will be installed. A survey will be administered, blood samples taken and blood pressure measured immediately prior to starting the filter, at 3 weeks when the filtration is changed from sham to real filtration or visa versa and at the end of the second three week period. All participants will be recruited from the Boston Puerto Rican Health Study cohort.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03187704
The ClinicalTrials.gov registry entry for NCT03187704 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 23 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Tufts University, which has 78 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 Cardiovascular Health appearing as the primary indexed condition, and to 1 intervention — of which HEPA air filtration 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: NCT03187704 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. 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.
