Information With or Without Numbers For Optimizing Reasoning About Medical Decisions
NCT02477553 · View on ClinicalTrials.gov ↗
Study Summary
Experts believe that increasing the low uptake of screening for colorectal cancer (CRC) requires educating patients about all approved tests and helping them choose one that fits their preferences. As one motto puts it: "The best test is the one that gets done." Screening tests range from more invasive and very sensitive for polyps and cancer (colonoscopy) to less invasive and less sensitive (e.g., fecal immunochemical testing (FIT)). But it is unclear how best to educate patients about the options and the tradeoffs involved. Some guidelines recommend that decision aids, a promising tool in this area, provide patients with detailed quantitative information, including baseline risk, risk reduction, and chance of negative outcomes. But this sort of "comparative effectiveness" data can confuse patients, especially those with limited mathematical ability. Previous studies have not measured the effect of providing quantitative information to patients with varying levels of ability or interest or asked them whether such data is essential for their decision-making. The investigators will conduct a clinical trial to determine the impact on patients who view a decision aid (DA) that includes quantitative information versus a DA without such data. The investigators will also seek to determine whether numeracy moderates the effect of quantitative information.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02477553
The ClinicalTrials.gov registry entry for NCT02477553 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 728 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Indiana University, which has 1,026 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 Colorectal Cancer Screening appearing as the primary indexed condition, and to 2 interventions — of which DA - Quantitative 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: NCT02477553 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.
