Table 2. Mendelian Randomization (MR) and Observational Analysis Estimate of the Associations of Myopia and Intraocular Pressure (IOP) With Retinal Detachment.
Exposure | MR method | OR (95% CI) | P value | Observational methoda | OR (95% CI) | P value |
---|---|---|---|---|---|---|
MSE | IVW | 0.72 (0.69-0.76) | 3.8 × 10−44 | Model 1 | 0.80 (0.78-0.83) | 2.5 × 10−55 |
IOP | IVW | 1.08 (1.03-1.14) | 1.1 × 10−3 | Model 1 | 1.05 (1.02-1.09) | 2.5 × 10−4 |
IOP | Multivariable MRb | 1.06 (1.01-1.12) | .03 | Model 2 | 1.03 (1.00-1.06) | .04 |
Abbreviations: IVW, inverse-variance weighted; MSE, mean spherical equivalent refractive error; OR, odds ratio.
In observational model 1, we adjusted for sex and baseline age in logistic regression models. In observational model 2, we adjusted for refractive error, sex, and baseline age.
Multivariable MR analysis, a regression-based MR method, to adjust for the effect of MSE refractive error.
