Patients with bullous pemphigoid (BP) have elevated galectin-9 serum levels. (a) Serum levels of galectin-9 measured by enzyme-linked immunoassay (ELISA) in patients with BP (n = 40) compared with healthy age- and sex-matched controls (n = 40). Bold lines of boxplots indicate the median; boxes illustrate lower and upper quartiles; whiskers show the lowest and highest data point still within 1.5× of interquartile range from lower or upper quartile, respectively; each dot represents an individual. Groups were compared by 2-sided Wilcoxon rank-sum test (p = 0.0002).
