From: Variability in detection and quantification of interferon β-1b–induced neutralizing antibodies
Scatter plot of reported titer levels. The number of valid results out of the 125 provided samples is given below each laboratory identifier. The gray bar indicates the median value, the black bar indicates the lower limit of quantification (LLOQ). Laboratories C and D had an upper limit of quantification, that is, values are censored. NAb = neutralizing antibody.
