Incidence rates and hazard ratios for knee osteoarthritis by atopic disease presence. This figure displays the incidence rates (IR) per 1,000 person-years and hazard ratios (HR) for knee osteoarthritis across different groups of atopic disease presence. The bars represent the incidence rates, while the lines represent the hazard ratios with 95% confidence intervals. Data are adjusted for age, sex, income, smoking, drinking, physical activity, diabetes mellitus, dyslipidemia, and hypertension. Atopic diseases include asthma, allergic rhinitis, and atopic dermatitis. CI, confidence interval.
