Mean relative bias of each imputation method and each parameter under different simulation scenarios. The missing data mechanism was MAR and \(C=4\). The missing rate was 20%. Each column represents one combination of parameters of interest, degrees of ICS, and ICC, with two different sample sizes. The black line is the reference line at 0; the grey line represents the results using the full data; the green line represents the results using complete case analysis; the blue line represents the results using FCS+CS; the red line represents the results using FCS; the purple line represents the results using JM+CS; the orange line represents the results using JM
