Although the interaction between BMI categories was marginally significant (P for interaction = 0.096), the overall impact of WWI ≥ 10.97 on OA risk was evident across all BMI groups.
Racial analysis identified the highest OA risk in the non-Hispanic White group with WWI ≥ 10.97 (OR 2.19, 95% CI 1.59 ~ 3.03), though the interaction between race and WWI did not reach statistical significance (P for interaction = 0.213).
