The median 50IT (ms) and its 95% CI (in square brackets) is given for each pinhole condition and each session. Differences between the first “no pinhole” condition and each of the remaining pinhole conditions (1−5 mm and the last condition with “no pinhole”) are also provided along with the 95% CIs.
