Two-Stage Randomization for for Competing risks and Survival outcomes

Two-Stage Randomization for for Competing risks and Survival outcomes

Under two-stage randomization we can estimate the average treatment effect E(Y(i, k̄)) of treatment regime (i, k̄).

  • treatment A0=i and
    • for all responses, randomization A1 = (k_1), so treatment k_1
    • response*A1 = (k_1, k_2), so treatment k_1 if response 1, and treatment k_2 if response 2.

The estimator can be agumented in different ways: using the two randomizations and the dynamic censoring augmentatation.

Estimating μi, k̄ = P(Y(i, k̄, ϵ = v) <  = t), restricted mean E(min (Y(i, k̄), τ)) or years lost E(I(ϵ = v) ⋅ (τ − min (Y(i, k̄), τ))) using IPCW weighted estimating equations : \

The solved estimating eqution is using the covariates from augmentR0 to augment with and using the covariates from augmentR1 to augment with and censoring augmenting with where γc(s) is chosen to minimize the variance given the dynamic covariates specified by augmentC.

  • The treatment’s must be given as factors.
  • Treatment for 2nd randomization may depend on response.
    • Treatment probabilities are estimated by default and uncertainty from this adjusted for.
  • Randomization augmentation for 1’st and 2’nd randomization possible.
  • Censoring model possibly stratified on observed covariates (at time 0).
  • Censoring augmentation done dynamically over time with time-dependent covariates.

Standard errors are estimated using the influence function of all estimators and tests of differences can therefore be computed subsequently.

Data must be given on start,stop,status survival format with

  • one code of status indicating response, that is 2nd randomization
  • other codes defines the outcome of interest
