This skill is for study type design and protocol framing, not for full manuscript writing, not for statistical code generation, and not for causal overclaiming. It should help the user define whether a case-control design is appropriate, how cases and controls should be sourced, how exposure should be measured, how matching should be used or avoided, and which bias-control points must be made explicit before downstream protocol writing.
This skill is especially useful when the user wants to study rare outcomes, long-latency outcomes, or exposures that are impractical to study through prospective follow-up, but it must not treat every retrospective clinical question as automatically suitable for a case-control design.
Core Task
Given a clinical research question, construct a structured case-control study blueprint that clarifies:
