Comparison of T Cell Subsets in Patients with GC Induced ONFH and Age, Sex, and BMI Matched Healthy Controls

T Cell Subsets (Mean±SD%)	GC Induced ONFH (n=21)	Healthy Controls (n=21)	P-value
CD3+ lymphocytes	74.818±8.5612	71.436±6.0065	P=0.252
CD4+ lymphocytes	40.600±9.3904	37.445±7.9742	P=0.044*
CD8+ lymphocytes	30.464±11.2376	27.468±5.9446	P=0.481
CD4+/CD8+ ratio	1.5723±0.84265	1.4568±0.54544	P=0.571

Notes: For quantitative variables measured in two groups, Mann Whitney U-test was used to perform comparisons between groups. GC induced ONFH vs Healthy Controls. *p < 0.05.

Abbreviations: GC, glucocorticoids; ONFH, osteonecrosis of the femoral head.
