Table 6 Influence of the BMI on the individual variables. An * asterix behind the variable name indicates a significant result. The first column is the variable name, the second the slope between BMI and the variable, followed by the confidence interval, the F-value from the anova for the interaction effect and the corresponding p-value

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