TGFβ, pg/mL (IQR) | 1357 (875–2031) | 2633 (1152–3317) | 708 (412–1587) | 1256 (652–3536) | ns |
Data are expressed as the median and interquartile range (IQR) and p is calculated according to the Kruskal–Wallis test. Dunn’s post hoc test: # p < 0.01, * p < 0.001 vs. OA, ° p < 0.05 vs. CIA, § p < 0.05 vs. RA. Abbreviations are as follows: OA, osteoarthritis; RA, rheumatoid arthritis; PsA, psoriatic arthritis; CIA, crystal-induced arthritis; ns, not significant.
