Laboratory or bench study
Explores mechanisms, materials, or performance under controlled conditions. It may support feasibility or biological plausibility but does not by itself prove benefit in people.

PURPOSE & AUDIENCE
For people who need to make sense of health information.
Intended audience: Patients, caregivers, community members, students, volunteers, nonprofit staff, early-career learners, and professionals seeking a general evidence-literacy refresher.
This introductory course is educational and does not teach diagnosis, treatment, regulated professional practice, or individualized medical decision-making. Participants should bring questions about personal care to an appropriately qualified healthcare professional.
Content responsibility: This is an institutional resource prepared by the ISO Metrik Institute Education Office. No individual clinical or scientific faculty member is currently represented as the course author, and no external accreditor has reviewed or approved the activity.
LEARNING OBJECTIVES
After completing EL-101, a learner should be able to:
- 01
Distinguish a health claim, research question, study result, interpretation, and recommendation.
- 02
Recognize common research designs and explain why each design supports different levels of inference.
- 03
Identify population, intervention or exposure, comparison, outcome, time, and setting in a study summary.
- 04
Separate statistical findings from clinical, practical, or personal importance.
- 05
Look for limitations, uncertainty, conflicts of interest, ethical oversight, registration, and access to full results.
- 06
Use a repeatable checklist to prepare questions before relying on a health claim.
Module 1
CLAIMS, QUESTIONS & EVIDENCE
Start by identifying what is actually being claimed.
A claim is a statement that something is true, useful, safe, effective, associated, better, or recommended. Evidence is the information offered to support or challenge that claim. A research question defines what investigators are trying to learn; a result reports what was observed; an interpretation explains what the result may mean; and a recommendation asks someone to act.
These are not interchangeable. A laboratory finding does not automatically establish a clinical benefit. An association does not automatically prove cause. A result in one population does not automatically apply to every person.
Practice question
What exact claim is being made, and is the source describing a hypothesis, an observed result, an interpretation, or a recommendation?
Module 2
STUDY DESIGNS
Match the strength of the conclusion to the design.
Case report or case series
Describes one or several experiences. It may identify a signal or generate a hypothesis but usually cannot establish how often an outcome occurs or what caused it.
Observational study
Examines patterns without assigning an intervention. It can identify associations but may be affected by confounding, selection, measurement, and other biases.
Randomized controlled trial
Assigns participants to comparison groups to reduce important sources of bias. Its usefulness still depends on design quality, size, adherence, outcomes, follow-up, and applicability.
Systematic review
Uses a defined method to identify and synthesize available studies. Its conclusions depend on the quality, consistency, relevance, and publication of the included evidence.
Expert opinion
May provide context and professional judgment but should be identified as opinion and not presented as a substitute for direct evidence.
Module 3
RELEVANCE & LIMITATIONS
Ask whether the evidence answers the question you have.
Find the population, setting, intervention or exposure, comparison, outcomes, and follow-up period. Then ask whether they match the people and decisions for which the claim is being used.
- Was the sample large and representative enough for the stated conclusion?
- Were outcomes meaningful, measured consistently, and reported completely?
- Was there an appropriate comparison group and sufficient follow-up?
- Were participants lost to follow-up, and could that change the result?
- Does the source distinguish relative change from absolute change?
- Are uncertainty, adverse events, alternative explanations, and limitations visible?
Remember
“Statistically significant” does not automatically mean large, important, clinically meaningful, or applicable to a particular person.
Module 4
SOURCE, OVERSIGHT & TRANSPARENCY
Evaluate how the work was conducted and reported.
Responsible interpretation includes more than the headline result. Look for investigator qualifications, institutional roles, funding, conflicts of interest, ethical or IRB review when human participants are involved, prospective registration when applicable, a stated analysis plan, and access to methods and full results.
A conflict of interest does not automatically invalidate research, but it should be disclosed and managed. Missing disclosures, selective results, changing outcomes after the fact, or conclusions that extend beyond the data are reasons to slow down and seek more information.
Module 5
APPLY THE FIVE-QUESTION CHECK
Use the same process every time.
- What exactly is the claim?Write it in one neutral sentence.
- What evidence directly supports it?Identify the design and whether the evidence is direct or indirect.
- Who and what were actually studied?Compare the study population, setting, intervention, outcome, and duration with the claim.
- What could change the interpretation?Look for uncertainty, bias, missing data, conflicts, limitations, and other explanations.
- What responsible next step follows?Seek the full source, compare evidence, ask a qualified professional, or wait for stronger evidence.
KNOWLEDGE CHECK
Complete all eight questions.
A score of at least 7 out of 8 is required to request the non-credit completion certificate. Open each item after selecting your answer to review the explanation.
1. An association between two variables automatically proves that one caused the other. Choose: True or False
Answer: False. Association may be influenced by confounding, selection, measurement, timing, or other explanations.
2. Which design is primarily used to explore performance under controlled, non-clinical conditions? A. Bench study · B. Randomized trial · C. Case series
Answer: A. A bench study can support mechanism or feasibility but does not by itself establish clinical benefit.
3. Why identify the population and setting? A. To judge applicability · B. To guarantee benefit · C. To remove all uncertainty
Answer: A. Applicability depends on how closely the studied population and context match the intended use.
4. Statistical significance always means the effect is important to patients. Choose: True or False
Answer: False. Magnitude, uncertainty, outcomes, risks, costs, preferences, and context also matter.
5. What should a health-claim review include? A. Limitations only · B. Benefits only · C. Benefits, risks, limitations, and uncertainty
Answer: C. Balanced review makes material strengths and limitations visible.
6. A disclosed conflict of interest automatically makes a study false. Choose: True or False
Answer: False. A conflict should be disclosed and managed; the methods, data, oversight, and reporting still require evaluation.
7. Which is the most responsible response to a conclusion that extends beyond the studied population? A. Accept it · B. Ask for direct evidence · C. Ignore all research
Answer: B. Ask whether direct evidence supports the broader claim.
8. A payment confirmation proves that an educational offering is accredited. Choose: True or False
Answer: False. Accreditation or professional-credit approval requires separate, explicit documentation.
COMPLETION CERTIFICATE

Processing target: 10 business days
Cost: $0
Credit: 0 CE/CEU/CME or academic credits
Meaning: Confirms completion only; it is not certification, licensure, board recognition, or authorization to practice.
SOURCES & LIMITATIONS
Use primary sources and qualified advice.
The course introduces general evidence-literacy principles and should be used with the full research report, applicable ethical and regulatory information, and qualified professional guidance. It does not evaluate a particular product, treatment, diagnosis, or individual circumstance.
