Plot of sample mean estimates of $\mathbb{P}({\text{ACR}}^{(24)}20=1)$ at each time point (6, 12, 18 and 24 months). Results are shown where multiple imputation has been performed using the ML method (MLE), linear increments method (LI), chained equations method (CHAINED) and direct imputation method (DIRECT). Results for the complete cases data (Complete) are also shown. Separate plots are shown for each of the four trial arms
