Multivariate analysis of the correlation between anti-spike IgG titers post-bivalent mRNA vaccine booster and fever after the primary series, monovalent booster, and bivalent booster. The data of 70 participants were available for inclusion in the analysis. Forest plots depict the results of a multivariate regression analysis examining the correlation between anti-spike IgG titers post-bivalent mRNA vaccine booster and fever after the primary series, monovalent booster, and bivalent booster. The standardized coefficients β with 95 % Confidence Intervals (CI) and p-values represent the strength and direction of the association between post-bivalent booster IgG titers and the listed variables, after adjusting for covariates. The dotted vertical line denotes the point of no association (β = 0), with coefficients to the right that suggest a positive association and to the left suggesting a negative association.
