§2.4Eligibility as the Institute reads it

• Included. Domain-specific cognitive function or protection against cognitive decline, assessed by standardised neuropsychological batteries or clinical dementia rating.
• Excluded. Participants for whom the intervention is contraindicated, including known hypersensitivity. Exclusion criteria narrow the population to which the estimate applies and are the principal source of indirectness where a trial estimate is applied to ordinary practice.
