Table 6 Chair comparison. Detailed presentation of the Bonferroni-Holm corrected p-values of the pair comparison (Conover-Iman test) after significant Chi2-values of the Friedman test. The chair-pairs between which there is a significant difference are shown, together with their p-values, first for all subjects and then for each individual group. Chair 1: Sirona CARL (Sib), Chair 2: Salli Saddle chair (Sal), Chair 3: Sirona Hugo Freehand (Sio), Chair 4: Aeris Swopper (Sw), Chair 5: KaVo Physioform 5005 (Kg), Chair 6: KaVo Evo (Kb)
