Use the source that fits the claim
Regulatory agencies establish device authorization and safety communications. Peer-reviewed research and systematic reviews inform clinical effects and limitations. Professional medical organizations support patient education. Manufacturer documentation establishes current product identity, formulation and instructions, with commercial claims labeled accordingly.
| Claim type | Preferred source | Required context |
|---|---|---|
| Clinical benefit | Relevant trials and systematic reviews | Population, intervention, comparator and outcome |
| Safety or authorization | Regulatory source and device labeling | Exact model, indication and market |
| Ingredients and directions | Current manufacturer documentation | Region and formulation version |
| Price or availability | Current official or reputable retailer listing | Currency, date and size |
| Original framework | Site methodology | Clearly labeled as editorial, not clinically validated |
Read beyond a headline
We check whether findings apply to the treatment and population being discussed. A positive combination study does not isolate each component. Small samples, heterogeneous protocols and limited follow-up are noted. We do not turn an abstract into a claim that the entire full text was critically appraised.
Traceable updates
Source links and a meaningful review date accompany reference content. Product and medical changes are tracked separately. Missing information is recorded as unknown; it is not filled with assumptions. New evidence should trigger a review of connected pages, not just the page where it was first found.
