Figure S1. Graphical representation of temporal patterns of viral shedding The attached graphs represent the smoothing curves of the delay: X = Days since symptom onset, Y = RT-PCR Cycle threshold (Ct) value. Comparison of RT-PCR initial Ct value and death at 1 month and comparison of a persistently RT-PCR positive test at 1 month and the Charlson Comorbidity Index were performed using the Mann-Whitney Wilcoxon Test. Oddsratio (OR), is the multiplication of the risk that PCR is positive at 1 month when the Charlson Index increases by 1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
