Table 3.

The means and standard deviations of the motion parameters MT and MR for the female and male participants under the air and carbogen breathing conditions. The numbers of subjects are shown in the parentheses. The p values were obtained from Wilcoxon’s rank sum tests comparing values between air and carbogen (A vs C) breathing conditions or between female and male (F vs M) subjects.
