For test of the null hypothesis that RNFL thickness is the same in the right and left eyes calculated using linear mixed model with random intercepts to account for correlation between eyes. A Bonferroni correction was applied due to multiple testing and P < 0.007 is considered statistically significant. Data from all 1288 participants in the analysis were included.
