Figures

Figure 1
Figure 1
Serum IgG4 level according to diagnosis. IgG subclass information was available for 50 of the 66 patients. Each boxplot has a median line, with the hinges marking the 25th and 75th percentiles, and whiskers extending at most to values 1.5 times the interquartile range. Exact values are overlaid as dot plots. Blue dots represent values for patients with histologically confirmed IgG4-RD. Dashed line: 1.25 g/L, upper limit of normal serum IgG4 level in our laboratory.
