CHALLENGE studied structured exercise, not a resistance-only intervention. Check intervention components and existing reviews before proceeding.
The package preserves effect-selection, dependency and missing-data decisions, input versions and reproducible code. No pooled estimate is invented.
Each conclusion links to screening, extraction, bias judgments and analysis. Non-poolable evidence receives a structured synthesis.
EOS’s internal system evaluation is a real process reference; commissioned roles, responsibilities and acceptance are scoped separately.
Customer situations are illustrative. Each sample explains the scope and limitations of its referenced data.

Show effect size and confidence separatelyPresent important outcomes, relative and absolute effects, available data and certainty, with reasons for downgrading.
GRADE evaluates a body of evidence for a particular outcome. Database inclusion or one study does not automatically establish high certainty.
These references support problem definition and evidence appraisal. Your conclusions still require project-specific sources and professional review.
