Fig. 3From: A comparison of multiple imputation methods for missing data in longitudinal studiesDistribution of the bias in the estimated regression coefficients (i.e., mean changes in the QoL z-score associated with each covariate) for analysis model (2) across the 1000 simulated datasets following complete data, available data and 12 multiple imputation methods. Top, left and bottom right panels show the distribution of the bias in the estimated regression coefficients for covariates with missing data and all other panels show the distribution of the bias associated with fully observed covariateBack to article page
