National, regional, and provincial prevalence of age-related macular degeneration in China in 2020: an updated systematic review and modelling study.

ABSTRACT:

Background

The burden of age-related macular degeneration (AMD) has steadily increased in recent decades. We aimed to estimate the prevalence of AMD, including its subtypes, among individuals aged 40-89 years in China.

Methods

For any AMD, we additionally conducted random-effects meta-analyses to pool odds ratios for assoc
