Methodology and limits
How to read a ProtocolRank ranking
ProtocolRank organizes evidence, cost, risk and practical tradeoffs. Its rankings are editorial judgments, not clinical recommendations or estimates of your chance of benefit. Use a ranking to identify questions and sources before making a purchase.
Is a high score the same as strong evidence?
No. A composite score combines judgments about evidence and practical factors. A lower-cost or easier-to-use approach can score differently even when its evidence is similar. The number is not a percentage improvement, a safety rating for you, or a validated clinical risk calculator.
Read the evidence discussion separately. Human outcomes, observational associations and biological mechanisms answer different questions. A plausible mechanism is a reason to investigate a claim; it does not by itself establish that a product improves health in people.
The paid guide describes five editorial dimensions. These explain the framework; they are not a claim that every public page has a complete, independently validated scorecard.
Evidence
What was studied, in whom, and with which outcomes?
Evidence for one population, outcome or product does not automatically establish a benefit for another.
Practicality
What time, skills, equipment and ongoing effort does the approach require?
An editorial assessment of feasibility is not a measured prediction of your adherence.
Risk burden
What adverse effects, uncertainties and interactions need attention?
A higher score does not mean an option is safe for a particular person or combination.
Cost
What are the upfront and recurring costs, including access and monitoring?
A value judgment is not a clinical cost-effectiveness study or a promise of money saved.
Combination and workload
How might the approach overlap with other activities, costs or recovery demands?
A discussion of combinations is not proof that a particular stack has been tested together.
How can I check the evidence behind a claim?
- Find the original source and its publication date. Check whether a later correction or retraction changes it.
- Record the study design, participant population, comparison group, outcome measured and follow-up period.
- Keep a measured outcome separate from the advertised claim. A laboratory marker and a long-term health outcome are different claims.
- Look for uncertainty, missing harms, funding and conflicts of interest. Absence of reported harm is not proof of safety.
- Check whether the page explains its conclusion and links the source that supports it. A year in the title or a numerical score does not replace that explanation.
These questions are consistent with the free source-evaluation guidance from MedlinePlus and the study-appraisal questions from NHLBI. Neither organization endorses ProtocolRank or validates its rankings.
What can a ranking not tell me?
It cannot determine whether an intervention suits your medical history, medications or circumstances. It does not prescribe a dose, diagnose a condition or establish the safety of combining interventions. Questions about individual suitability belong with a qualified healthcare professional.
A summary can omit context. Follow the linked sources and distinguish what a study observed from the editor's interpretation. Treat a missing source, unexplained score or unsupported claim as a reason to seek more information, including on this site.
Coverage, updates and commercial context
ProtocolRank's stated editorial standard is to explain uncertainty and link primary sources for factual health claims. Older pages do not all meet that standard. This methodology page does not certify that every article has received a fresh literature search, independent clinical review or a completed audit.
The About page states that protocol creators and commercial partners cannot buy ranking position. ProtocolRank offers a paid guide and may earn through commercial relationships described in its Terms of Use. Consider disclosures and the original evidence when evaluating any recommendation.
What does the $19 guide add?
The one-time purchase is a personal-use educational PDF with editorial protocol comparisons, references and planning worksheets. It puts the material in one document. It does not include a clinical service, personalized protocol, subscription or hosted app. Check the guide page for the current contents and access terms before purchasing.
