NCT00011674 · View on ClinicalTrials.gov ↗
Study Summary
This prospective cohort study examines the role of prenatal and early postnatal lead exposure on the neuropsychological status and social adjustment of adolescents enrolled in the Cincinnati Lead Study. We are examining the relationship between moderate exposure to lead and neuropsychological deficits, difficulties in peer relationships, personality disturbances and juvenile delinquency. This birth cohort of approximately 300 subjects has been followed since 1980 with regularly scheduled assessments of blood lead concentrations, health history, social and hereditary factors, and neurobehavioral development.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00011674
The ClinicalTrials.gov registry entry for NCT00011674 describes a study currently listed as completed. 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 300 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Environmental Health Sciences (NIEHS), which has 75 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Lead Poisoning appearing as the primary indexed condition, and to 0 interventions. 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: NCT00011674 reports 1 study location spanning 1 distinct geographic area — top geographies include Ohio. 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.
