Table 7.

Comparison of mMPTA, mLDFA between the clamping + bone traction device group and the clamping + traction bed group ( $\bar{x}$ ±s).

Group	Number of cases	mMPTA (°)			mLDFA (°)
Group	Number of cases	Preoperative	1 month after surgery	3 months after surgery	Preoperative	1 month after surgery	3 months after surgery
Clamping + bone traction device	69	84.33 ± 5.51	87.63 ± 4.41^a^, ^b	90.82 ± 5.53^a^, ^b^, ^c	83.93 ± 6.21	88.92 ± 7.44^a^, ^b	91.62 ± 7.73^a^, ^b^, ^c
Clamping + traction bed	69	83.79 ± 6.34	85.55 ± 5.57^a^, ^b	88.40 ± 4.12^a^, ^b^, ^c	83.62 ± 6.58	85.51 ± 8.05^a^, ^b	88.34 ± 7.25^a^, ^b^, ^c
F_Inter-group P	–	31.635/<0.001
F_{Time Point} P	–	126.871/<0.001
F_{interaction between groups and time points} P	–	9.362/<0.001

Comparisons with the clamp + traction bed group at the same time point indicate statistically significant differences.

^{^a}

P < 0.05, vs. the same group before surgery.

^{^b}

P < 0.05, vs. the same group 1 month after surgery.

^{^c}

P < 0.05, vs. the same group 3 months after surgery.
