Table 1.
Correlation coefficients for IgG against different betacoronaviruses in the prepandemic (n = 70), COVID-19 ICU (n = 86), and integrated prepandemic + COVID-19 ICU (n = 156) cohorts. The color marks cells with a significant level of correlation coefficients for IgG against different betacoronaviruses.
