Figure 5.

Correlation between ELISA and Maglumi methods in vaccinated subjects after the first dose. The trend lines represent the Passing–Bablock correlation. (a) Concentrations expressed in the respective units of each manufacturer [Maglumi= −0.89 (−6.1/+1.2) + 0.59 (0.47/0.78) ELISA. (b) Concentrations expressed as binding antibodies units [Maglumi = −5.1 (−26.8/+5.0) + 0.82 (0.64/1.07) ELISA]. Regression line (solid line), confidence interval lines (dashed lines) and identity line (dotted line) are displayed. Circles represent the single cases.
