Text: The adjusted hazard ratios (HRs) for association of progression to cataract surgery at 5 years were : nuclear cataract increase of 1. 0 unit or more compared with less than 1. 0-unit change at 2 years, 2. 77 (95 % confidence interval [CI], 2. 07-3. 70 ; P < 0. 001) ; cortical cataract increase of 5 % or more in lens opacity in the central 5 mm of the lens compared with less than 5 % increase at 2 years, 1. 91 (95 % CI, 1. 27-2. 87 ; P = 0. 002) ; and posterior subcapsular cataract increase of 5 % or more versus less than 5 % in the central 5 mm of the lens, 8. 25 (95 % CI, 5. 55-12. 29 ; P < 0. 001).
