Comparison of the duration of viral RNA shedding and anti-SARS-CoV-2 spike IgG and IgM antibody titers in COVID-19 patients who were vaccinated with inactivated vaccines or not: a retrospective study

Table2 Viral RNA Shedding Duration Correlated with Ct Value, Specific IgG and IgM Titers

	Viral shedding duration after illness onset (days)	P
Ct value	r = − 0.249	0.002
SARS-CoV-2 specific IgG titer	r = − 0.421	0
SARS-CoV-2 specific IgM titer	r = − 0.341	0

Correlation analysis was performed using the Spearman method. Spearman correlation coefficient was represented by the r value. A P value of less than 0.05 (two-tailed) was considered statistically significant
ct, SARS-CoV-2 nucleocapsid gene cycle threshold (ct) value
