How We Find, Evaluate, and Report Research
This page explains exactly how Clinical Study Connect identifies, assesses, and presents the clinical research featured on this site. Transparency about our methods allows you to evaluate the quality and limitations of our work.
Step 1: Study Identification
We identify relevant studies through systematic searches of recognized research databases and repositories, including:
- PubMed / MEDLINE (National Library of Medicine)
- ClinicalTrials.gov (U.S. National Library of Medicine trial registry)
- Cochrane Library (systematic reviews and meta-analyses)
- Google Scholar (broad academic search)
- Institutional and university research repositories
- Regulatory filings and safety databases (FDA, EFSA, WHO)
We prioritize studies that:
- Have been published in peer-reviewed journals
- Involve human participants (when available)
- Study ingredients commonly found in health supplements, functional foods, or botanical products
- Have clearly described methodology, outcomes, and funding
Step 2: Quality Assessment
Not all studies are created equal. Before including a study in our coverage, we assess its quality across multiple dimensions:
Study Quality Assessment Framework
| Study Design | Is this an RCT, observational study, case report, or preclinical research? The design type determines what conclusions can and cannot be drawn. |
| Sample Size | How many participants were included? Smaller studies are more likely to produce results that do not replicate. |
| Population | Who was studied? Age, health status, geographic location, and other demographics affect whether findings apply to you. |
| Controls | Was there a control group? Was the study blinded? Placebo-controlled, double-blind studies produce more reliable results. |
| Duration | How long did the study last? Short-term studies may miss effects that take weeks or months to appear. |
| Outcomes | What was actually measured? Were the outcomes clinically meaningful or based on surrogate markers? |
| Conflicts | Who funded the study? Do the authors have financial ties to the ingredient or product manufacturer? |
| Replication | Have other independent researchers found similar results? Single unreplicated studies are inherently less reliable. |
Step 3: Evidence Synthesis
For each ingredient or research topic, we look beyond individual studies to assess the overall body of evidence. This means:
- Identifying patterns — Do multiple studies point in the same direction, or do results conflict?
- Noting consistency — Are positive findings from one study confirmed by others, or are they isolated?
- Evaluating progression — Has the research moved from animal/cell studies to human trials? What stage is it at?
- Acknowledging gaps — What questions remain unanswered? What populations or doses have not been studied?
Step 4: Plain-Language Reporting
Clinical studies are written for other researchers. Our job is to translate them for everyone else without distorting what they found. We follow these principles:
- Use the study’s own words for findings — We do not upgrade “may support” to “supports” or “preliminary evidence” to “proven”
- State limitations alongside findings — If a positive result came from a 12-person study with no control group, we say that
- Distinguish types of evidence — Cell studies, animal studies, and human studies are clearly labeled as such
- Avoid false precision — We do not present ranges or general findings as exact numbers unless the study did
- Explain what results mean in practical terms — Where possible, we explain what a finding might mean for a consumer considering the ingredient
Step 5: Limitation Disclosure
Every study summary and ingredient evidence page on this site includes explicit disclosure of:
- The limitations of the studies cited
- What the evidence does not prove
- What remains unknown or insufficiently studied
- Whether the evidence is from ingredient-level research or finished-product testing
- Any disclosed funding sources or author conflicts of interest
We believe that telling you what we do not know is just as important as telling you what we do know. An honest assessment of the limits of current research is essential for making informed decisions.
Step 6: Review and Updates
Research is not static. New studies are published, existing studies are retracted or corrected, and scientific understanding evolves. We maintain our content through:
- Scheduled reviews — High-interest ingredient pages are reviewed at minimum every 180 days; educational content every 365 days
- Triggered updates — Study retractions, major new findings, or regulatory safety alerts prompt immediate review
- Correction transparency — All corrections are noted with dates and described on the affected page
What Our Methodology Cannot Do
Our research methodology is designed to produce accurate, transparent summaries of available clinical evidence. It is not a substitute for systematic reviews conducted by research institutions, regulatory assessments by agencies like the FDA or EFSA, or individualized medical guidance from a qualified healthcare provider. We present the published evidence as clearly as we can. What you do with that information is a decision best made with the help of someone who knows your health situation.
