The Relationship Between Vitamin D, Fingernail Thickness and Bone Density
NCT00006196 · View on ClinicalTrials.gov ↗
Study Summary
Vitamin D deficiency is common in the elderly and contributes to the increased incidence of falls, hip fracture and depression in this population. An unknown number of elderly have vitamin D resistance resulting in a functional vitamin D deficiency state. Because there are no simple procedures or blood tests that identify vitamin D resistance, its prevalence and contribution to disability in the elderly is unknown. Our inability to screen for this condition precludes our ability to initiate and monitor treatment. Previous studies indicate that fingernail thickness correlates with vitamin D status and may therefore provide a simple cost effective procedure to not only identify patients with vitamin D deficiency but also, those with vitamin D resistance. This procedure may also provide a way to monitor an individual's response to treatment. This study is designed to demonstrate the association between fingernail thickness and vitamin D status.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00006196
The ClinicalTrials.gov registry entry for NCT00006196 describes a study currently listed as completed. It is categorized as Phase 1, 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. An enrollment target was not published in the registry record, which is common for early-stage or observational entries. The listed sponsor is National Center for Research Resources (NCRR), which has 20 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 Osteoporosis appearing as the primary indexed condition, and to 1 intervention — of which Vitamin D 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: NCT00006196 reports 1 study location spanning 1 distinct geographic area — top geographies include Missouri. 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.
