Figure 3 shows a comparison of PAR scores for each treatment group compared at
each post-treatment time point. There was a statistically significant difference in PAR
scores between treatment groups at DCR4 (p<0.01). No other time points showed any
differences between early treatment groups.

Figure 3. Comparison of PAR scores between treatment groups at each post-treatment
timepoint. B=Bionator, C=Control, H=Headgear/Biteplane. Medians, inter-
quartile ranges and outliers are shown. Timepoint with a significant
difference between treatment groups (DCR4) is highlighted with an asterisk.
Figure 4 shows differences in PAR scores between early treatment groups
compared at each post-treatment time point from DCF (DCF minus DCR). PAR scores
increase as negative occlusal changes occur, therefore negative values indicate occlusal
changes (relapse) were occurring whether they be significant or not. There were

Figure 4 shows differences in PAR scores between early treatment groups
compared at each post-treatment time point from DCF (DCF minus DCR). PAR scores
increase as negative occlusal changes occur, therefore negative values indicate occlusal
changes (relapse) were occurring whether they be significant or not. There were
significant differences between treatment groups in amount of relapse occurring between
DCF and DCR1 (p<0.05) as well as between DCF and DCR4 (p<0.05).
