Prediction model and multivariate regression. (a) Mean Decrease Accuracy shows the relative degree to which a factor improves the accuracy of the forest in classification prediction. (b) Mean Decrease Gini assigns a weight of importance to each parameter, which improves accuracy of the prediction. (c) A receiver operating characteristic curve (ROC curve) based on random forest algorithm predicts COVID-19 patients develop septic shock. (d) Independent significant factors for septic shock in hazard ratio analysis based on a multivariate logistic regression model show that hypnotics (HR = 0.096, ) were the only protecting factor.
