Figure 6.

Correlation of serum FSTL1 levels with ESR (n = 199), CRP (n = 207), RF (n = 207), ACPA (n = 206), tender (n = 81) and swollen (n = 81) joint counts, patient global VAS score (n = 81) and patient DAS28 score (n = 81) in adult RA population. Correlation coefficients (r) and P values from the Spearman rank-order test are displayed. Each point represents an individual value. FSTL1, follistatin-like protein 1; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein; RF, rheumatoid factor; ACPA, anti-cyclic citrullinated peptide antibody; VAS, visual analogue scale; DAS28, Disease Activity Score 28; RA, rheumatoid arthritis.
