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.
