Robust linear mixed model comparing the differences in distance judgement error during the blind walking test between the CTL and BVL subject groups. For the fixed effects, the robust estimation down-weighted 18% of the residuals. For the random effects, the robust estimation down-weighted 13% of the residuals; the analysis included 359 observations in 60 subjects. * <i>p</i> < 0.05.
