Association between reduction of RNFL thickness in the superior quadrant and cognitive deterioration in stable participants.

Cognitive function	Non-adjusted		Adjusted

The left panel of the table illustrates the results of the regression coefficients for the changes of RNFL thickness and cognitive function in a simple linear regression. The right panel of the table shows the regression coefficients in multiple linear regressions including adjustment of age, gender, education, blood glucose, and cholesterol levels. TS, test score; IS, index score.
