IL-6	1.91 (1.28, 3.03)	1.77 (1.52, 3.78)	-0.669	0.503
IL-10	0.94 (0.63, 1.14)	1.12 (0.95, 1.27)	-2.522	0.012
IL-1	2.68 (2.59, 3.40)	2.99 (2.59, 3.40)	-1.280	0.201
IFN-γ	11.25 (10.57, 13.06)	10.90 (10.90, 12.32)	-0.330	0.742
IL-4	3.32 (2.02, 3.32)	3.32 (2.02, 3.32)	-0.252	0.801

IL-2	6.18 (4.35, 7.54)	5.88 (5.03, 7.06)	-0.334	0.738
IFN-α	1.85 (1.70, 2.00)	2.00 (1.96, 2.00)	-2.033	0.042
IL-12	129.96 (110.96, 150.45)	145.24 (117.95, 150.45)	-0.847	0.397

Mann-Whitney U test (non-parametric) was used to compare inflammatory cytokine levels between the low- and high-risk groups. Data are presented as median, with Z and P values reported. TNF: Tumor necrosis factor; IL: Interleukin; IFN: Interferon.
