The proportion of missing data should not be used to guide decisions on multiple imputation.
TL;DR: Evidence is provided that for MAR data, valid MI reduces bias even when the proportion of missingness is large, and researchers are advised to use FMI to guide choice of auxiliary variables for efficiency gain in imputation analyses, and that sensitivity analyses including different imputation models may be needed if the number of complete cases is small.
