Histograms of the variables at 24 months used to calculate ${\text{ACR}}^{(24)}20$. ‘TRUE’ denotes the true values, ‘MLE’ denotes values imputed by ML-based models and ‘LI’ denotes values imputed using linear increments models. Missingness was simulated at 12, 18 and 24 months, prior to multiple imputation
