Table B1.
Summary of missingness for the study population of 2,289 patients. Predictors with no missing values were not included in this table for conciseness. Predictors with greater than 30% missing data were excluded from the analysis. Missing values of predictors included in the analysis were imputed by mean (for continuous variables) or mode (for categorical variables).
