The value of C3 in identifying TA disease activity. a The distribution of C3 in different levels of Kerr score. b The scatter plot of C3, ESR, CRP, and disease activity (blue line—the cut-off reference line of C3 and CRP; dot size—ESR; dot colour—disease status, “red” indicates active disease status, “green” indicates inactive disease status). c The summary of C3, CRP, ESR, and disease activity in different subgroups based on the cut-off value. d The ROC curve of C3 to distinguish the disease activity
