Table 5 Test statistic for the comparison of all variables by gender. An * asterix behind the variable name indicates a significant result. The first column is the variable name, the second the median of the difference of the female and male subjects, followed by the confidence interval, the t-value from the student’s t-test, the estimated standard deviation and the probability based on the degree of freedom of 798

From: Systematic changes of the static upper body posture with a symmetric occlusion condition
