Differences between true regression estimates and imputed regression estimates (A) as well as differences between association p-values (B) for 6 imputation methods. Evaluations were done on randomly selected 10 and 40 proteins from complete data (296 proteins with no missing values). Global missingness of 10 to 40% was introduced for each individual protein list. Regressions were computed with all imputed data regardless of their distance from truth
