Editorial index: substances classified under age context. This index does not assert a combined effect. Age-defined study groups can differ in drug disposition. Age associations need study-specific interpretation.

- Diphenhydramineindexed substance
Age-group differences in one syrup study were not replicated in a lower-exposure experiment; no universal age multiplier is assigned.

Relationship nodes connect multiple concepts in one sourced statement. Member roles identify the substance, biological target, measured outcome, or exposure context. Editorial index relationships group classifications. Connections are not recommendations to combine substances.
