Linear regression was used to assess the association between OCT-A and retinal thickness measures, adjusted for confounders of sex, age, medical history of hypertension, diabetes and the quality index of OCTA image. RNFL, retinal nerve fiber layer; GCC, ganglion cell complex. The GCC refers to the complex of the macular fovea, 7 mm from the ILM to the IPL. The inner retina is from ILM to IPL and the outer retina is from INL to RPE. The bold values indicate statistical significance. **p < 0.01.
