^aNumber of missing data: V_TOT (4), V_PERIPH (4), mean sensitivity (4)

^bInclude participants with baseline VTOT >5 dB-sr

^cTests with false positive rate <15%

^dOutliers were down-weighted using weighted mixed-effects model, weights were computed from robust regression modelling of estimate rate of decline from each participant

^eAll P-values for testing the average annual change estimates against zero were <0.001
