Correlation between ELISA and Maglumi methods in vaccinated subjects 3 months after the second dose. The trend lines represent the Passing–Bablock correlation. (a) Concentrations expressed in the respective units of each manufacturer [Maglumi= −16.2 (−37.5/+5.7) + 0.78 (0.65/0.98) ELISA]. (b) Concentrations expressed as binding antibodies units [Maglumi = −72.8 (−166.8/+24) + 1.07 (0.88/1.35) ELISA]. Regression line (solid line), confidence interval lines (dashed lines) and identity line (dotted line) are displayed. Circles represent the single cases.
