TABLE 1. Characteristics of the Study Population.
This table shows the characteristics of the subjects. Subjects were divided into 3 groups (tertiles) based on baseline ACI. Age shows the mean age (in years) and standard deviation (in parenthesis) for each tertile group. Gender shows how many in each tertile were male; numbers in parenthesis shows percent male. Race shows how many in each tertile were white; number in parenthesis shows percent white. Baseline AREDS Nuclear Grade shows the mean nuclear lens grade for each tertile; numbers in parenthesis show the standard deviation. Follow up time show the mean follow up time for each tertile group in months; numbers in parenthesis show standard deviation.
| Overall | ACI>=10.8 (23 eyes, 17 patients) |
ACI 6.1–10.8 (26 eyes,15 patients) |
ACI <6.1 (17 eyes,13 patients) |
