Reading note
Keep the description of an exposure beside the claim it is being used to support. Formulation, application and setting are details to compare when moving between reports. If a hypothetical claim carries evidence from one context into another, identify that transition explicitly rather than treating the ingredient name as the whole description. Ask what information connects the contexts and what remains untested by the cited comparison. The resulting note should make the boundary visible without declaring either that transfer is justified or that it is impossible.

Questions to take to the evidence
- Which exposure details accompany the evidence presented for this claim?
