Figure 2
Restricted cubic spline curves presenting the adjusted hazard ratio for incident retinal vein occlusion and retinal artery occlusion according to age at menopause. Solid lines represent hazard ratio and dashed lines indicate 95% confidence interval based on restricted cubic splines for age at menopause with knots at the 5th, 35th, 65th, and 95th percentiles and reference point at the 5th percentiles of the distribution. The risk of retinal vein occlusion and retinal artery occlusion continuously decreased as age at menopause increased in Cox proportional hazard model fully adjusted for age, income level, systemic comorbidities, behavioral factors, and female reproductive factors (model 3).
