Comparison of imputation methods for handling missing covariate data when fitting a Cox proportional hazards model: a resampling study

BACKGROUND: The appropriate handling of missing covariate data in prognostic modelling studies is yet to be conclusively determined. A resampling study was performed to investigate the effects of different missing data methods on the performance of a prognostic model. METHODS: Observed data for 1000...
