RE is defined as the ratio between the estimated variances of the CC estimator and the other estimators. The variables birthwt, wt4mon, wt8mon, wt1yr and MatBMI stand for baby’s birth weight, baby’s 4-month weight, baby’s 8-month weight, baby’s 1-year weight and mother’s pregnancy BMI respectively. CC, IPW, FI, FIIPW, MI and MIIPW are imputation approaches
