Censored survival data are common in clinical trial studies. We propose a unified framework for sensitivity analysis to censoring at random in survival data using multiple imputation and martingale, called SMIM. The proposed framework adopts the δ-adjusted and control-based models, indexed by the sensitivity parameter, entailing censoring at random and a wide collection of censoring not at random assumptions. Also, it targets a broad class of treatment effect estimands defined as functionals of…

Control-based imputation for sensitivity analyses in informative censoring for recurrent event data.
The control-based multiple imputation as sensitivity analyses for the recurrent event data is implemented and the number of events after dropped out is imputed and the variance estimation is correct using a bootstrap procedure.

This report uses semiparametric theory to develop an estimator for differences in restricted mean lifetimes although accounting for confounding factors and shows that the proposed estimator possesses the double robust property; i.e., when either the time-to-event or coarsening process is modeled correctly, the estimator is consistent and asymptotically normal.
Comparison Between Two Controlled Multiple Imputation Methods for Sensitivity Analyses of Time-to-Event Data With Possibly Informative Censoring
Controlled imputation methods provide general and flexible sensitivity analyses to address nonignorable missing data. For time-to-event data with possibly informative censoring, we compare two
On analysis of longitudinal clinical trials with missing data using reference-based imputation
The statistical properties of RBI methods are investigated, and approaches to derive accurate variance estimates using both frequentist and Bayesian methods for the RBI analysis are proposed.
Causal inference on the difference of the restricted mean lifetime between two groups.
Estimators for the difference of the restricted mean lifetime between two groups that account for treatment imbalances in prognostic factors assuming a proportional hazards relationship are proposed and large-sample properties of these estimators based on martingale theory for counting processes are derived.
Analysis of Longitudinal Trials with Protocol Deviation: A Framework for Relevant, Accessible Assumptions, and Inference via Multiple Imputation
This article sets out an accessible framework for contextually appropriate assumptions relevant to de facto and de jure estimands, that is, assumptions about the joint distribution of pre- and postdeviation data relevant to the clinical question at hand, and shows how multiple imputation provides a practical approach to estimation and inference.
Sensitivity to censored-at-random assumption in the analysis of time-to-event endpoints.
This work discusses how the methods that are widely used for primary analyses of time-to-event outcomes could be extended in a clinically meaningful and interpretable way to stress-test the assumption of ignorable censoring and concludes that the method based on piecewise exponential imputation model of survival has some advantages over other methods studied here.
Marginal structural models to estimate the causal effect of zidovudine on the survival of HIV-positive men.
The marginal structural Cox proportional hazards model is described and used to estimate the causal effect of zidovudine on the survival of human immunodeficiency virus-positive men participating in the Multicenter AIDS Cohort Study.
Multiple-Imputation Inferences with Uncongenial Sources of Input
When it is desirable to conduct inferences under models for nonresponse other than the original imputation model, a possible alternative to recreating imputation models is to incorporate appropriate importance weights into the standard combining rules.
A note on multiple imputation for method of moments estimation
Multiple imputation is widely used for estimation in situations where there are missing data. Rubin (1987) provided an easily applicable formula for multiple imputation variance estimation, but its
