Original Approach for Automated Quantification of Antinuclear Autoantibodies by Indirect Immunofluorescence
Figure 5
Correlation between fluorescence index and ANA titer. Calculated indices from patients with ANA positive speckled pattern () were plotted as a function of the endpoint titer. The box plots show the median value and range from the first to the third quartile. The whiskers extend between the maximum and the minimum indices. There is a correlation between the fluorescence index and the fluorescence endpoint titer (Spearman’s , ).
