Table 3.
Proportion of people with significant changes in National Eye Institute Visual Function Questionnaire-25 scores for individuals with 2 or more line changes in best corrected visual acuity of the better seeing eye as determined by the reliable change index.
| Change in visual acuity between Los Angeles Latino Eye Study baseline and follow-up examinations |

RCI= Reliable change index. VA=visual acuity.
Bolded number and percent indicate those NEI-VFQ scores with a large (30% or greater) percent of individuals with statistically significant change in score in the same direction as the direction of VA change.
Note: Percentage is for each line change group. For example, 31 participants increased 2 lines best corrected better seeing eye visual acuity, 11 (11/31=35.48%) participants had RCI between less than or equal to −1.96 subscale general health.
LALES = Los Angeles Latino Eye Study. NEI-VFQ-25 = National Eye Institute Visual Function Questionnaire.
