The 20 Most Important Groups of Predictors of Risk Ranked by Random Forest Feature Importance. Sub-predictors from the same group (e.g., Healthcare occupation) have been separated and rearranged for visual clarity. Positive coefficients that are statistically significant (risk increasing) are in blue, and negative ones are in orange. More detailed descriptions of each factor and variable are available in the Appendix. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
