Cell contributions
Large contributions identify cells that depart most from independence. They do not by themselves explain why.
Canvas focus question: Report the two observed risks, relative risk, statistical conclusion, and one sentence that avoids a causal overclaim.
Biblical/Ethical Stewardship and Integrity: Use transparent denominators, avoid fear-inducing language, and consider the people represented by every count. Association should never be presented as proof of causation.
