Emulation sensitivity and feasibility
Evaluate deviations and identifying assumptions
Assess support, protocol-to-data deviations, measurement error and residual confounding. Restrict the target question when the available data cannot support it. TARGET reporting guidance does not certify that causal assumptions hold.
Flow diagram
Steps
Review protocol deviations
Link each target-to-data mismatch to a plausible bias pathway.
Assess empirical support
Evaluate eligible episodes, outcomes, observation and treatment overlap.
Plan measurement sensitivity
Vary justified code definitions, timing and exposure grace rules.
Plan causal sensitivity
Address unmeasured confounding, informative censoring and optional negative controls.
Document feasible claims
Retain limitations and unsupported estimands alongside primary specifications.

Specify alternatives before outcome-driven selection.
Assumptions and rationale
Sensitivity analyses assess fragility; they do not certify causal identification.
