Heterogeneous Treatment Effects: Validate the Average Effect Before Trusting the Subgroups
A practical guide to validating heterogeneous treatment-effect claims in target trial emulation. Learn why a failed average-effect benchmark should stop a subgroup story, how subgroup effects must reconcile with their parent estimate, and what reviewers should demand before trusting personalized treatment claims.
Benchmarking Target Trial Emulation: When a Trial Copy Never Checks It Can Reproduce the Known Answer
A practical guide to benchmarking target trial emulation for clinical researchers. Covers why benchmark replication matters, what it cannot prove, and what reviewers should demand before trusting an observational extension.
Repeated Eligibility in Target Trial Emulation: When One Patient Quietly Enters the Trial Again
A practical guide to repeated eligibility in target trial emulation for clinical researchers. Covers re-entry rules, overlapping follow-up, carryover, and what reviewers should demand before trusting a sequential-trial analysis.
Time Zero Alignment: When Your Cohort Starts Counting Before Treatment Does
A practical guide to time zero alignment for clinical researchers. Covers eligibility, treatment assignment, delayed initiation, immortal time, and what reviewers should demand before trusting a real-world effect estimate.
Grace Periods in Target Trial Emulation: Clinical Realism or Future Information in Disguise?
A practical guide to grace periods in target trial emulation for clinical researchers. Covers when a grace window is defensible, when it becomes immortal time in formalwear, and what reviewers should demand before trusting the result.
Clone-Censor-Weight: The Target Trial Fix That Still Breaks When You Use It Casually
A practical guide to clone-censor-weight for clinical researchers. Covers when the design is needed, how cloning and artificial censoring work, where immortal time bias reappears, and what reviewers should demand before trusting a target trial emulation.
Target Trial Emulation: A Practical Guide for Clinical Researchers
The framework that bridges observational data and causal claims — by asking what RCT you wish you had. Covers protocol specification, time zero alignment, clone-censor-weight, immortal time bias, and reporting.
