Table 3 summarizes both study groups mean VPS values (s), its CI 95% and the p-values obtained from comparing both samples for each of the 3 eccentricities. On the other hand, it includes for each study group, the mean VPS % of change values and the p-values obtained from each one of the 3 possible two-by-two comparisons among the 3 eccentricities
