Table 4 Serum antibody at 3 months after SARS-CoV-2 diagnosis was correlated with age. Multiple linear regression analysis was performed considering serum antibody titers at 3 months after SARS-CoV-2 diagnosis as a dependent variable. Predictors entered in the analysis were: age, gender, presence or absence of symptoms, and Orf1ab Ct values at diagnosis
