Your question is Diagnose Drop in Patient Outcome Metrics. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

If a key patient outcome metric suddenly drops after a rollout at UCB, how would you diagnose the cause? Treat this as a practical analytics investigation: validate the metric, isolate when and where the change occurred, distinguish data issues from real patient impact, and recommend next actions. Explain the analyses, comparisons, and guardrails you would use.
