Variable	AUC	Z test	p
IL-6	0.56 (95% CI: 0.27-0.84)	0.38	NS
IL-8	0.74 (95% CI: 0.52-0.97)	2.12	< 0.05
TGF-β1	0.76 (95% CI: 0.56-0.97)	2.55	< 0.01
CRP	0.64 (95% CI: 0.32-0.96)	0.85	NS
ESR	0.62 (95% CI: 0.32-0.92)	0.76	NS
WBC	0.58 (95% CI: 0.29-0.86)	0.52	NS

IL-6 – interleukin-6, IL-8 – interleukin 8, TGF-β1 – transforming growth factor β1, CRP – C-reactive protein, ESR – erythrocyte sedimentation rate, WBC – white blood cell count
