The cohort of unrelated individuals comprised a total of 213 age-related cataract cases and 104 clear lens controls, matched for age and gender. Cases with both nuclear and cortical cataracts (32) were counted in both the any cortical and any nuclear groups. Cases with any posterior sub-capsular cataracts (17) were not analyzed separately due to statistically insufficient numbers.
