The formula is verified. Causal interpretation still requires a defensible study design, comparison and assumptions.
Keep the same place, observation period, definitions, units and source versions.
Analysis inputs. Treatment Verified research recommendation uptake before [%]; Treatment Verified research recommendation uptake after [%]; Comparison Verified research recommendation uptake before [%]; Comparison Verified research recommendation uptake after [%]; Study design and comparability evidence; Outcome definition, method and reference basis
Other required evidence. Research output; uptake; institutional action; outcome; external factors; follow-up.

The arithmetic alone does not establish causation. Design, parallel trends, confounding, attrition, uncertainty and adverse effects need appropriate evidence.
Proposed checking role. Principal investigator, statistician and ethics/data-access reviewer.
After the action. Verified outcomes, costs, distributional effects and evidence strength.
