Further, the CSVD model showed a larger AUC (0.823, 95% CI: 0.781\u20130.866) than the brain atrophy model (AUC\u2009=\u20090.757, 95% CI: 0.706\u20130.808).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Microvascular and neurodegeneration are significantly associated with DR.
