Comparison between CLNT and FRNT measurements.

<p>(A) Correlation between 50% Ad5 neutralizing antibody titers (log₁₀) of 144 human sera positive by CLNT and FRNT assays. The line represents the fitted regression line. (B) Bland-Altman plot of Ad5NAb measurements using the CLNT and FRNT assays. Solid line indicates the mean value, and dashed lines represent 95% confidence limits. The x-axis indicates the average of Ad5NAb titers (log₁₀) of CLNT and FRNT assays. The y-axis indicates the difference between the Ad5NAb titers (log₁₀) of CLNT and FRNT assays.
