Research
System.
Every health or science claim should be traceable. We do not rewrite another site's conclusion and call that research.
THE WORKFLOW
Claim → source → appraisal → language.
Each evidence-based article begins with explicit claims. We seek the strongest relevant sources available, evaluate limitations, then write language proportionate to the evidence.
Evidence matrix
EDITORIAL FRAMEWORK| LEVEL | MEANING | USAGE |
|---|---|---|
| A · STRONG | Consistent support from high-quality guidelines, systematic reviews or converging evidence. | Clear language, with scope and caveats. |
| B · MODERATE | Useful support, but limitations, heterogeneity or fewer high-quality studies. | Qualified language; avoid overgeneralizing. |
| C · LIMITED | Small studies, mixed results, indirect evidence or important methodological concerns. | Present as preliminary or uncertain. |
| D · TRADITIONAL / SPECULATIVE | Historical belief, expert opinion or hypothesis without sufficient empirical support. | Label it clearly; do not present as established fact. |
