Overview of retrospective diagnostic test accuracy studies. Papers are binned per hospital setting, data are sorted in ascending order of AUROC values. AUROC ranges are displayed per paper. AUROC area under the curve of the receiver operating characteristic, SVM support vector machines, GLM generalized linear model, NB Naive Bayes, EM ensemble methods, NNM neural network model, DT decision trees, PHM proportional hazards model, LSTM long short term memory, Hrs bef. onset hours before onset * DT, EM, GLM, LSTM, NB, NNM, SVM
