Antioxidant multivitamin and mineral supplement probably leads to lower progression to late AMD (neovascular AMD, geographic atrophy, or both) compared with placebo or no treatment (moderate certainty).
Antioxidant multivitamin and mineral supplement probably leads to lower progression to neovascular AMD compared with placebo or no treatment (moderate certainty).
Antioxidant multivitamin and mineral supplement showed no clear difference in progression to geographic atrophy compared with placebo or no treatment (moderate certainty).
Antioxidant multivitamin and mineral supplement probably leads to lower progression to visual loss (loss of 3 or more lines on logMAR chart) compared with placebo or no treatment (moderate certainty).
