Find harmonized census and health-survey data with documentation for comparative research. Data access is free but requires project registration and adherence to use conditions; some projects require further approval.
Causal question specification
State the contrast a nonrandomized analysis is intended to estimate.
Cohort time-zero alignment
Align eligibility, exposure assignment and follow-up start to prevent immortal-time errors.
Confounder selection evidence matrix
Choose adjustment variables using causal roles and measurement timing.
Selection and collider pathway audit
Identify selection rules that can open misleading exposure–outcome associations.
Mediator adjustment decision record
Distinguish total-effect questions from pathways involving post-exposure variables.
Exposure support map
Check whether each relevant covariate pattern permits the exposure comparisons being proposed.
Negative-control rationale worksheet
Document what a negative-control result can and cannot reveal about bias.
Exposure classification sensitivity plan
Explore how imperfect exposure labels could affect the study comparison.
Outcome ascertainment comparability
Check whether groups have equivalent opportunities for an outcome to be detected.
Active-comparator selection record
Choose a comparison group that represents the same treatment decision.
Target-population transport worksheet
Assess whether a study result can inform a different population.
