Important determinants for RT-qPCR and RAT results by random forest classification model
As shown in Figure S1, It was found that the sampling time post-symptom onset was the most significant parameter that determines the results in both assays. The order of importance of other parameters differed between the RT-qPCR and the RAT. Dyspnea and radiological findings were the top two parameters for the RT-qPCR results, whereas subject’s age and chest pain were the most important features for the RAT.
