The computer-assisted embedding method was used to screen the variables. The random forest algorithm was adopted to build a rapid screening model based on the training set. The screening model was evaluated by the confusion matrix and receiver operating characteristic (ROC) analysis in the validation.The rapid screening model was set up basedMedicineMulticenter analysis and a rapid screening model to predict early novel coronavirus pneumonia using a random forest algorithm.PMC82133132020C03123Wang MSXie XSShi JCWu WHHui TCShen YFPan HYDai YNTong YXYin QQWu LJZhang JJHuang HJTu WHYan RYu LXBao SZheng WHuang YCYu WJJu BSun NNChen MJChen GBMa CLWu QQFang NfalseMulticenter analysis and a rapid screening model to predict early novel coronavirus pneumonia using a random forest algorithm.<h4>Abstract</h4>Early determination of coronavirus disease 2019 (COVID-19) pneumonia from numerous suspected cases is critical for the early isolation and treatment of patients.The purpose of the study was to develop and validate a rapid screening model to predict early COVID-19 pneumonia from suspected cases using a random forest algorithm in China.A total of 914 initially suspected COVID-19 pneumonia in multiple centers were prospectively included.
