Simulation results for 7 different strategies: Non-informative censoring (NIC), complete case analysis (CC), multiple imputation before ascertainment (MI), multiple imputation after ascertainment (MI (asc.)), IPW estimates after ascertainment with constant weights (IPW (asc,cw)), logistic regression based weights (IPW (asc,lw), and Bayesian model averaging weights (IPW (asc,maw)). Levels of ascertainment relate to the percentage of missing outcome information that was ascertained.
