In Figures 2 through 5, the terms ‘Favours treatment’ and ‘Favours control’ placed below the x-axis of the forest plots should not be taken into consideration upon observation of the Figures. These terms are placed automatically by the meta-analysis program used, i.e. all reduction of values measured are considered by the program as favouring the treatment group, while the opposite as favouring the control group. For Class II treatment, these categories are correct for changes in SNA, ANB and OJ, but incorrect for changes in SNB (since an increase of SNB favours treatment).
