The average time for nucleic acid detection results to become negative was 27.29±7.73 days for sputum samples, 27.82±12.09 days for oropharyngeal swab samples, and 24.53±13.59 days for saliva samples (see Appendix Table 4 ). Multivariate analysis found that clinical classification had a significant impact on the time of sputum and oropharyngeal swab samples to become negative (p=0.007, p=0.002) (see Appendix Table 5 ). The overall sensitivity, efficiency and specificity of saliva-sputum combined detection method were 93.40%, 94.00% and 95.20%, respectively (see Appendix Table 6 ). 1,5-9 total efficiency and specificity of the saliva detection method in this study were higher than those of the sputum and oropharyngeal swab detection methods (83.90% and 94.40%, respectively). ./cache/cord-317315-yyssvbbl.txt ./txt/cord-317315-yyssvbbl.txt
