From: Increased production of soluble CTLA-4 in patients with spondylarthropathies correlates with disease activity

Figure 2

Correlation between soluble Cytotoxic T Lymphocyte Antigen- 4 (sCTLA-4) and clinical index of disease activity Bath Ankylosing Spondylitis Disease Activity Index in 165 patients with spondylarthropathies. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was evaluated as described in [19]. The statistical test used was Spearman's r test. When the eight extreme values (white circles) are not considered for correlation analysis, a significant correlation between sCTLA-4 and BASDAI score is still observed: (Spearman's test: r = 0.382, P < 0.0001).
