Imputed data distribution based on MI-wCQR 2. Distribution of biomarker data from one of simulated datasets, distinguishing observed data (green area; data with left-censored/missing values) from imputed data (gray area); after imputation, data distribution was very similar to the complete data distribution that were originally simulated (red line)
