Scatterplots of calprotectin (a, d), ESR (b, e), and CRP values (c, f) with corresponding clinical disease activity index (CDAI) values in tocilizumab (TCZ)-treated RA patients (a–c) and in tumor necrosis factor alpha-inhibitor (TNFi)-treated (d–f) RA patients. Significant correlations were detected between calprotectin and CDAI in TCZ- (a) and TNFi-treated patients (d), as well as between ESR (e) and CRP (f) with CDAI in TNFi-treated patients
