Computationally efficient inference for center effects based on restricted mean survival time. Another causal estimand is a variation of the the restricted mean survival time (RMST) and captures the length of the delay in the nonterminal event among always-survivors.

Restricted mean survival time (RMST) is often of great clinical interest in practice. Restricted Mean Survival Times. Directly modeling RMST (as opposed to modeling then transforming the hazard function) is appealing computationally and in terms of interpreting covariate effects.

Several existing methods involve explicitly projecting out patient-specific survival curves using parameters estimated through Cox regression. Any kind of data, as long as have enough of it. We consider the design of such trials according to a wide range of possible survival distributions in the control and research arm (s). The restricted mean survival time is estimated in strata of confounding factors (age at diagnosis, grade of tumor differentiation, county median income, date at diagnosis, gender, and state). However, it would often be preferable to directly model the restricted mean for convenience and to yield more directly interpretable covariate effects. If you do not receive an email within 10 minutes, your email address may not be registered, In this report, we develop weighted estimators of the complier average causal effect (CACE) on the restricted mean survival time in the overall population as well as in an evenly matchable population (CACE‐m). RMST is the patient's life expectancy until time t and can be estimated nonparametrically by the area under the Kaplan-Meier curve up to t. … Restricted Mean Survival Times. Through simulation studies, we show that the proposed estimators tend to be more efficient than instrument propensity score matching‐based estimators or IPIW estimators. Restricted mean survival time analysis.
