Correlation analyses of anti-spike Ab with neutralization titers of the sera from 39 kidney transplant recipients against the different SARS-CoV-2 variants by simple linear regression. The correlation was performed by Pearson’s analysis. The concentrations of anti-spike Ab showed a strong correlation with the neutralization titer for each variant. The Pearson r was 0.72, 0.57, 0.67, 0.68, and 0.71 for the Delta, Omicron BA.1, Omicron BA.2, Omicron BA.4, and Omicron BA.5 variants, respectively; p < 0.0001.
