In this simulation study, performing a CC analysis with any multivariate missingness produced less biased regression coefficient estimates with better coverage rates than using SI or MI.

For the highly skewed continuous covariates X2, X3 and X4, the least biased regression coefficient estimates were produced when MI was performed using MICE-PMM without transformations.
