Correlation between cfDNA and blood oxygen levels. Blood was obtained from COVID-19 patients within 6 h of admission, followed by serum isolation. Total cfDNA isolated from serum was analyzed by qPCR for the quantification of cf-nDNA and -mtDNA. Scatter plots show the correlation between SpO2 and (a) cf-nDNA, and (b) cf-mtDNA; between SpO2/FiO2 ratio and (c) cf-nDNA, and (d) cf-mtDNA.
