Fig. 4: Autoantibodies targeting G protein-coupled receptors.

A Serum levels of autoantibodies targeting G protein-coupled receptors (GPCRs) of clinical relevance by treatment arm (HC: n = 45, placebo week 0: n = 21, placebo week 24: n = 21, RTX HR week 0: n = 11, RTX HR week 24: n = 11, RTX LR week 0: n = 13, RTX LR week 24: n = 13). B The heatmap illustrates correlation between the autoantibodies targeting GPCRs and clinical traits of SSc. *: P < 0.05, **: P < 0.01, ***: P < 0.001. P values were calculated by Spearman’s correlation test.
