  1. V vertical training group, H horizontal training group; HFD hemianopic field defect; IQR interquartile range; ft Friedman test; w post hoc Wilcoxon signed-rank test; Z test-statistics (Wilcoxon signed rank test), n number of cases, p significance value. Correlations correlations between reading speed of printed text (RS-print) horizontally with the EM variables; n number of patients. Spearman Rho Spearman’s rank correlation coefficient (Spearman's ρ), Pearson r Pearson product-moment correlation coefficient.
  2. In cases where the data were non-normally distributed, Spearman’s Rho was calculated, otherwise Pearson’s r.
