14.Using ANOVA we tested for differences in implant and control subjects in acoustical and kinematic parameters in the absence of load (implant turned off).We found no systematic differences between these groups in first (p > 0.95) or second formant frequency (p > 0.97) or in jaw protrusion (p > 0.53) or elevation (p > 0.11).We further assessed possible differences between implant and control subjects in acoustical and kinematic precision by computing their respective coefficients系数of variation变化 (CV),which are measures of variability normalized by the mean.Figures 5c and 5d plot the CVs of the first two formants and the CVs of protrusion and elevation.The individual data points give null condition values of the CV for each utterance and each subject separately.No differences in CV between implant and control subjects were found for either the first or the second formant frequency (p > 0.68 and p > 0.31,respectively) or for horizontal水平 jaw position (p > 0.95).For vertical垂直的 jaw position,control subjects were found to have a marginally轻微地 greater CV (p = 0.06).
