Association between knee OA and pain-related traits and two IL15RA SNPs.

Trait	IL15RA SNP
	rs2228059 (effect allele = C)	rs7097780 (effect allele = G)
Radiographic severity: K/L grade 2 vs. grades 3 + 4	OR = 0.98 (0.75–1.27)	OR = 1.19 (0.90–1.57)
Symptomatic vs. asymptomatic knee OA	OR = 1.02 (0.76–1.36)	OR = 1.48 (1.10–1.98), p = 0.0098
Neuropathic pain post-TJR	OR = 0.76 (0.63–0.92), p = 0.005	OR = 0.94 (0.76–1.15)

Odds ratios (OR) are adjusted for age, sex, and BMI. Bold values indicate statistically significant results (p < 0.01).
