B, The percent changes in evaluated inflammatory cytokines after eight weeks on ibrutinib treatment compared to pre-treatment levels. In both panels, median with interquartile range is shown. See supplementary table for complete list of tested cytokines/chemokines and changes over time. Statistical analyses were by Wilcoxon matched-pairs signed rank test. Asterisks indicate degree of statistical significance compared to pre-treatment levels: * P < .05, ** P < .01, *** P < .001, and **** P < .0001.
